Question

Can someone help me with this?

Answer 1

62.8 square units

Explanation:

`\theta = (2)/(5) \pi = (2)/(5) * 180 \degree = 72 \degree \\ \\ area \: of \: sector \\ = ( \theta)/(360 \degree) * \pi {r}^(2) \\ = ( 72 \degree)/(360 \degree) * \pi * {10}^(2)\\ = ( 1)/(5) * \pi * 100 \\ = 20\pi \\ = 20 * 3.14 \\ = 62.8 \: units^(2)`
