Ans 13:- TSA of sphere = 4 × pie × r ^2
=> 98.56 = 4 × 22/7 × r^2
= > 98.56 × 7 / 22 × 4 = r^2
= > root 7.84 = r
=> 2.8 cm. ...............Ans
HOPE IT WILL HELP YOU. . . . . . . . . .

I know 13 only buddy
Answer : 13)
Given that curved surface area of the sphere = 98.56 cm2.
i.e.,4×pie×r2 = 98.56
r2 = 98.56/4×22 ×7
= 24.64 ×7/22
= 1.12×7
r2 = 7.84
r = root 7.84
= 2.8cm
then, the radius of the sphere = 2.8cm.
I hope my answer is useful for you and please mark my answer as brainliest
