The formula for volume of a sphere is \frac{4}{3}  \pi r^{3}
To get radius from diameter, we must divide it by 2. 10/2=5, meaning the radius is 5 in.
Now, we just need to plug the values into the equation.
\frac{4}{3}  \pi 5^{3} =  \frac{4}{3}  \pi 125 = 166.67 \pi = 523.61 in^{3}

To find the volume of a sphere, you need the formula which is V=4/3(pi)r^3(r cubed). since radius equals to one-half of diameter. Since the beach ball's diameter is 10 inches, 10/2=5 <= radius. 5 cubed is 125 and 4/3 multiplied by 125 equals 166.67( i rounded to the tenths). Your volume will equal 166.67pi
( if you wanted in numbers than it will be around 523.438in cubed

The circumference is 28.26, what is the radius and area?
Shalnov [3]

Answer:

The radius is 4.5, while the area is equaled to 63.585

Step-by-step explanation:

Formula of circumference: radius times 2 times pie (3.14)

Formula of Area of Circle: radius squared times pie (3.14)

Divide 28.26 by 2 and by pie (3.14) to get the radius. You should get 4.5.

Square 4.5 (the radius), which should equal to 20.25. Then, multiply it by pie (3.14), which is equaled to 63.585. This is the area of the circle.
