Question

The diameter of a cylinder is 5 yd. The height is 4 yd. What is the volume of the cylinder

Answer 1

78.5 yd

Explanation:

=
`\pi`r²h

= (3.14)(2.5)²(4)

= (3.14)(6.25)(4)

= 19.625 x 4

= 78.5 yd

Answer 2

25 pi square yd OR rounded pi to 3.14: 78.5 square yd

Explanation:

Use the formula volume of cylinder = base area × h to determine the value of the base area.

Diameter: 5 yd

Height: 4 yd

(5/2)^2 Pi x 4 = 25 pi square yd.
