A snowball has a radius of 7cm. What is the volume of the snowball?
BabaBlast [244]

Answer:

The volume is 1436.8in^2 .

Step-by-step explanation:

-To find the volume of a sphere, you need the formula:

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

-Use the radius for the formula:

V = \frac{4}{3} \pi 7^3

-Then, you solve:

V = \frac{4}{3} \pi 7^3

V = \frac{4}{3} × \pi × 7^3

V = \frac{4}{3} \pi × 343

V = \frac{1372}{3} \pi = 1436.755

-Round the answer to the nearest tenth:

V = 1436.8

So, therefore the volume is 1436.8in^2 .

Charra [1.4K]

Number of people adopted a mantee through Fia's foundation = 40

30% more are people adopted a manatee

Number of people adopted = 30% of 40 = (0.30)(40) = 12

People adopted a manatee this year = number of people + 30% of 40

People adopted a manatee this year = 40 + 12

People adopted a manatee this year = 52
