Answer 1

SA: 2
`\pi`rh+2
`\pi r^2`

1. Find the radius. R = 1/2D

12 x 1/2 = 6

Radius is 6.

2. Plug in radius and height into equation.

SA: 2(3.14)(6)(10) + 2(3.14)(6^2)

3. Solve.

6 x 10 = 60

60 x 3.14 = 188.4

188.4 x 2 = 376.8

36 x 3.14= 113.04

113.04 x 2 = 226.08

4. Add them together.

376.8 + 226.08 = 602.88

Answer: 602.88 square centimenters

Answer 2
