Question

find the radius of the sphere whose surface area is area is 36piecm2​

Answer 1

Answer:

Pls mark me as brainliest

Step-by-step explanation:

Surface Area = 4*pi*r^2

36 = 4*pi*r^2

r^2 = 9/pi

r = 3/sqrt(pi)

calculate using calculator the remaining answer mate :)

Answer 2

Answer:

Area of a sphere = 4πr^2 ...... Formula

Area of sphere = 36π...... Given

36π = 4πr^2

r^2 = 36π

4π

r^2 = 9

r = 3 cm
