Answer:

Step-by-step explanation:

Area = πr^2

r = √(area/π)

r = √(28.26/3.14)

r = 3

and we know that,

d = 2r,

d = 2 x 3 = 6

Can someone help me out plz ??!

Answer:

≈ 62.8

Step-by-step explanation:

Using the equal ratios of

$\frac{areaof circle}{areaofsector}$ = $\frac{circleangle}{sectorangle}$ , that is

$\frac{100\pi }{sector}$ = $\frac{2\pi }{\frac{2\pi }{5} }$ = 5, thus

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

sector = 20π = 20 × 3.14 = 62.8 units²
