Question

THE SURFACE AREA OF SPHERE IS 515 CM WHAT IS THE RADIUS

Answer 1

Given:

area of sphere = 515πcm

To Find:

Radius

Solution:

515π=4πr×r

515=4×r²

515/4=r²

128.75=r²

√128.75=r²

11.35=r

Answer:

radius is 11.35 cm

Answer 2

Find : radius of the sphere

solution : surface area of the sphere = 4πr²

515 = 4*22/7*r²

r² = 3605/88

r = √3605/88
