Please help? The interior of a bowl is hemispherical. If the radius is 20 centimeters, approximately how many liters of liquid will it hold?

[(4/3)pi(40)cubed/1000](1/2)

[(4/3)pi(20)cubed x 1000(1/2)

[(4/3)pi(40)cubed x 1000](1/2)

[(4/3)pi(20)cubed/1000](1/2)

[(4/3)pi(10)cubed x 1000](1/2)

well lots of maths here... 

1. find the volume of the sphere 

$$V = \frac{4}{3} \pi r^3$$


2. halve the answer to get the volume of a hemisphere


3. use the fact 1cm^3 = 1mL
