Question

Find the radius of a sphere whose surface area is
$616 {m}^{2}$
​

Answer 1

Answer:

the radius of the sphere is 7 m.

Step-by-step explanation:

Data:

Surface area of sphere = S = 616 m²

Radius of sphere = r = ?

Solution:

We know that,

Surface area of the sphere = S = 4 π r²

Substituting the values, we get:

616 = 4 (22/7) r²

616 = (12.57) r²

r² = 616 / 12.57

r² = 49

r = √49

r = 7 m

which shows that the radius of the sphere is 7 m.
