Question

Dk how to do this can sm1 explain

Answer 1

Area of sphere = πr²
36π = πr²
Divide both side by π

36π/π= πr²/π
36 = r²
r = 6

Answer 2

`V = (4)/(3)\pi r^3\\r^3 = (3V)/(4\pi)\\r = \sqrt[3]{(3V)/(4\pi)}`

`r = \sqrt[3]{(3*36\pi)/(4\pi)} = \sqrt[3]{3*9} = \sqrt[3]{27} = 3` m

Answer: B (3 m).
