Question

Can someone help me out plz ??!

Answer 1

≈ 62.8

Explanation:

Using the equal ratios of

`(areaof circle)/(areaofsector)` =
`(circleangle)/(sectorangle)`, that is

`(100\pi )/(sector)` =
`(2\pi )/((2\pi )/(5) )` = 5, thus

5 × sector = 100π ( divide both sides by 5 )

sector = 20π = 20 × 3.14 = 62.8 units²
