Hey there! I'm happy to help!
To find the surface area of a sphere, here is what you do.
You square the radius.
4²=16
You multiply by 4.
16×4=64
And you multiply by pi!
64×π=64π
Therefore, the surface area of the sphere is A. 64π units². It's that easy!
Now you can find the surface area of a sphere! Have a wonderful day! :D
Here....
The length is given 15 feet and the width is 12 feet...Now let's find the Perimeter..
- The formula to calculate Perimeter of rectangle is 2 ( l + b )
Perimeter = 2 ( l + b )
= 2 ( 15 + 12 )
= 2 × 27
= 54 feet
