Geometry Formulas 2

Question 1

What is the area of a trapezoid with parallel sides of 6 and 10 and a height of 4?

Accepted Answer

32

Answer

Area = ½(b1 + b2)h = ½(6 + 10)(4) = 32.

Question 2

What is the circumference of a circle with radius 7? (use π ≈ 3.14)

Accepted Answer

43.96

Answer

Circumference = 2πr = 2(3.14)(7) = 43.96.

Question 3

What is the volume of a cube with edge length 5?

Accepted Answer

125

Answer

Volume of a cube = s³ = 5³ = 125.

Question 4

What is the area of an equilateral triangle with side length 4? (use √3 ≈ 1.732)

Accepted Answer

6.93

Answer

Area = (√3/4)s² = (1.732/4)(16) ≈ 6.93.

Question 5

What is the surface area of a sphere with radius 3? (use π ≈ 3.14)

Accepted Answer

113.04

Answer

Surface area = 4πr² = 4(3.14)(9) = 113.04.
