What is the volume of a sphere with diameter 5.5 m, to the nearest cubic meter?
a. 87m^3
b. 90m^3
c. 95m^3
d. 101m^3

The formula for volume of a sphere is V = 4/3 x PI x r^3

r = half the diameter = 5.5 /2 = 2.75

Using 3.14 for PI, the formula becomes:

V = 4/3 x 3.14 x 2.75^3

Volume = 87.07

Rounded to the nearest cubic meter, answer is A. 87 m^3

answer: -2+√x,-2-√x
