27+5= 32 total square feet.
32/4= 8 square feet per roll.
The volume of a sphere is given by the equation

, where r is the radius.
We are given the diameter of the sphere, but recall that the diameter is twice the radius:

. So the radius is half of the diameter:

.
Half of 8 cm is 4 cm.
We substitute this for r in the equation and we use 3.14 for <span>π.</span>
Step-by-step explanation:
130 percent
Of means multiply
P * 800 = 1040
Divide by 800
P * 800/800 = 1040/800
P = 1.3
Multiply by 100 to get percent
130 percent
If the 8 you’re talking about is in inches then it would be 16 feet but if it’s 8 feet then it’s 4 inches
