Its C. Because he uses 56 gallons with the normal shower head but only uses 24 with the saving one. 56-24+32

The diameter of the circle is given to be 10 units. We are to find the radius.

The diameter is always the twice of radius. If d represents the diameter and r represents the radius, we can write:

d = 2r

or

r = d/2

For d=10,

r = 10/2 = 5 units

So, the radius of the circle will be 5 units
