surface area of a sphere is 616
4*pie*r^2=616
4*(22/7)*r^2=616
r^2=49
r=7
4*pie*r^2=616
4*(22/7)*r^2=616
r^2=49
r=7
right answer Krishna bhai

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.
