<u>Answer:
</u>
The diameter of a sphere is 6ft 6in. The radius of sphere is 3 feet 3 inches.
<u>Solution:
</u>
Given that the diameter of sphere is 6 feet 6 inches.
We have to find the radius of the sphere.
The relation between diameter and radius of sphere is given as

Therefore, 

Radius = 3 feet 3 inches.
Hence the radius of the sphere is 3 feet 3 inches.
A.) True - Both cones and Pyramids have only one base
3 (3 + x) = 5x - 25
9 + 3x = 5x - 25
Add 25 to each side
34 + 3x = 5x
Subtract 3x from each side
34 = 2x
Divide each side by 2
17 = x
