Question

What is the diameter of a sphere if the surface area is 616?

Answer 1

since we know that the surface area of sphere is 4 Pi R Square it is given that surface area of sphere is 616 so which implies that 616 is equals to 4 into 22 by 7 into 8 Square from this you will get our and we know that diameter is equal to twice of r

Answer 2

here your answer
surface area of sphere is =616
4πr^2=616
4*22/7r^2=616
r^2=616*7/22*4
r^2=616*7/88
r^2=7*7
r^2=49
r=✓49
r=7
diameter =2*radius
diameter =2*7
diameter =14
