Question

Help me on this one please​

Answer 1

Area is 616 square centimeters.

Explanation:

Area of Circle

`A = \pi r^2`

A ... area

r ... radius

Given

r = 14 cm

Use formula.

`A = \pi r^2`

`A = \pi (14 \text{ cm})^2`

`A = \pi (196) \text{ cm}^2`

Use
`(22)/(7)` for
`\pi`, since they tell you to use that in instructions.

`A = ((22)/(7)) (196) \text{ cm}^2`

`A = 616 \text{ cm}^2`

Answer 2

615.8

Explanation:

Circle area = π * r² = π * 196 [mcm²] ≈ 615.8 [cm²]
