Question

5) Surface area of a sphere is 616sq cm. find its radius​

Answer 1

Answer:

Step-by-step explanation:

Data:

Surface area of sphere = S = 616 cm²

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 cm

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

Hope it helps.

Thanks.
