The surface area of a ball is 3,600x square millimeters. what is the ball's radius?
recall the formula sa=42
15 mm
21 mm
30 mm
450 mm

30 mm

Step-by-step explanation:

Given,

Surface Area of ball =

We have to find out the radius of the ball.

Solution,

Since the formula of Surface area is 4 times π times square of the radius.

We can frame it as;

Now on substituting the values, we get;

On dividing both side by 'π' using division property, we get;

On dividing both side by '4' using division property, we get;

Now taking square root on both side, we get;

Hence The radius of the ball is 30 mm.

answer;
