Flashcard 1: What is the perimeter of a rectangle with l=9 and w=4?
Answer: 26. Apply the perimeter formula P=2l+2w with given dimensions.
Flashcard 2: State the formula for the perimeter of a rectangle with length l and width w.
Answer: P=2l+2w. The perimeter sums all sides of the rectangle, equivalent to twice the length plus twice the width.
Flashcard 3: State the formula for the area of a rectangle with length l and width w.
Answer: A=lw. The area is calculated by multiplying the length by the width to cover the rectangular region.
Flashcard 4: State the formula for the area of a triangle with base b and height h.
Answer: A = rac{1}{2}bh. The area derives from half the product of the base and height, accounting for the triangular shape.
Flashcard 5: State the formula for the area of a parallelogram with base b and height h.
Answer: A=bh. The area is the product of the base and corresponding height in the parallelogram.
Flashcard 6: State the formula for the area of a trapezoid with bases b1,b2 and height h.
Answer: A = rac{1}{2}(b_1+b_2)h. The area uses the average of the two bases multiplied by the height.
Flashcard 7: State the formula for the circumference of a circle with radius r.
Answer: C=2extπr. The circumference measures the circle's boundary as twice the product of π and the radius.
Flashcard 8: State the formula for the area of a circle with radius r.
Answer: A=extπr2. The area fills the circle using π times the radius squared.
Flashcard 9: State the formula for the volume of a rectangular prism with dimensions l,w,h.
Answer: V=lwh. The volume is the product of length, width, and height to fill the prism.
Flashcard 10: State the formula for the volume of a cube with side length s.
Answer: V=s3. The volume cubes the side length since all dimensions are equal.
Flashcard 11: State the formula for the volume of a cylinder with radius r and height h.
Answer: V=extπr2h. The volume multiplies the circular base area by the height.
Flashcard 12: State the formula for the volume of a triangular prism with triangle area B and length L.
Answer: V=BL. The volume extrudes the triangular base area along the prism's length.
Flashcard 13: State the formula for the volume of a pyramid with base area B and height h.
Answer: V = rac{1}{3}Bh. The volume takes one-third of the base area times the height due to the tapering shape.
Flashcard 14: What is the area of a rectangle with l=12 and w=5?
Answer: 60. Multiply length by width using the rectangle area formula.
Flashcard 15: What is the area of a triangle with b=14 and h=6?
Answer: 42. Use half the product of base and height for the triangle area.
Flashcard 16: What is the area of a trapezoid with b1=8, b2=12, and h=5?
Answer: 50. Average the bases and multiply by height for the trapezoid area.
Flashcard 17: What is the circumference of a circle with radius r=7? Leave the answer in terms of \pi.
Answer: 14\pi. Multiply twice π by the radius for the circumference.
Flashcard 18: What is the area of a circle with radius r=3? Leave the answer in terms of \pi.
Answer: 9\pi. Square the radius and multiply by π for the circle area.
Flashcard 19: What is the volume of a rectangular prism with l=8, w=3, and h=5?
Answer: 120. Multiply length, width, and height for the prism volume.
Flashcard 20: What is the volume of a cube with side length s=6?
Answer: 216. Cube the side length to find the cube's volume.
Flashcard 21: What is the volume of a cylinder with r=2 and h=10? Leave the answer in terms of \pi.
Answer: 40\pi. Multiply the base area πr2 by height for the cylinder volume.
Flashcard 22: What is the area of a square with perimeter P=36?
Answer: 81. Divide perimeter by 4 to find side length, then square it for area.
Flashcard 23: What is the width w of a rectangle with perimeter P=50 and length l=15?
Answer: 10. Solve P=2l+2w for w by subtracting 2l from P and dividing by 2.
Flashcard 24: What is the height h of a triangle with area A=30 and base b=12?
Answer: 5. Solve A=21bh for h by multiplying area by 2 and dividing by base.
Flashcard 25: What is the volume of a pyramid with base area B=27 and height h=9?
Answer: 81. Apply one-third of base area times height for the pyramid volume.
