Please consider the graph of the sphere.

We know that the volume of sphere is equal to $\frac{4}{3}\pi r^3$ , where r represents radius of sphere.

We can see that diameter of sphere is 30 inches. We know that radius is half the diameter, so radius of the given sphere would be half of 30 inches that is $\frac{30}{2}=15$ inches.

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

$V=\frac{4}{3}\pi (15\text{ in})^3$

$V=\frac{4}{3}\pi \times 3375\text{ in}^3$

$V=4\times 1125\pi \text{ in}^3$

$V=4500\pi \text{ in}^3$

Therefore, the volume of the given sphere is $4500\pi\text{ in}^3$ and option B is the correct choice.

Answer:

$24

Step-by-step explanation:

1/4x + 1/3x + 8 = 22

1/4x + 1/3x = 7/12x

7/12x + 8 = 22

22 - 8 = 14

7/12x = 14

14/ 7/12

x = 24

A cyclist rides 8 miles in 32 minutes. What is the speed of the cyclist in miles per hour?

Neko [114]

Well 32 minutes is half of an hour so 8 miles would be half of the full x miles
so 8 x 2 would be 16
16 miles per hour
