Question

O GEOMETRY Volume of a sphere The radius, R, of a sphere is 8.3 mm. Calculate the sphere's volume, V. Use the value 3.14 for , and round your answer to the nearest tenth. (Do not round any intermediate computations.) Explanation Check 0 3 mm X 5 ?

Answer 1

ANSWER

2393.9 mm³

EXPLANATION

The volume of a sphere of radius R is,

$V=\frac{4}{3}\pi R^3$

In this case, the radius of the sphere is 8.3 mm. Using π = 3.14, the volume is,

$V=\frac{4}{3}\cdot3.14\cdot8.3^3mm^3=2393.881573\text{ }mm^3\approx2393.9\text{ }mm^3$

Hence, the volume of the sphere is 2393.9 cubic millimeters, rounded to the nearest tenth.
