Question

What is the approximate area of the shaded sector?

A. 38 cm2
B. 96 cm2
C. 302 cm
D. 603 cm?

Answer 1

C.
`302 \: {cm}^(2)`

Explanation:

`Area \: of \: sector = ( \theta)/(360 \degree) * \pi {r}^(2) \\ \\ = (135 \degree)/(360 \degree) * \pi {r}^(2) \\ \\ = (135 )/(360 ) * 3.14 * {(16)}^(2) \\ \\ = (108,518.4 )/(360 ) \\ \\ = 301.44 \\ \\Area \: of \: sector \approx \: 302 \: {cm}^(2)`
