Question

Volume of a circle equation?

Calculate the volume of liquid in the round flask sketched below. Give your answer in liters, and round to the nearest .

the diameter of the flask is 22.0 cm

Answer 1

There is no formula for a volume of a circle. Volume of a sphere is:
V=4/3 · π · r³. In this case: r=11.0 cm = 1.1 dm
V= 4/3 · 3.14 · 1.1³ =1.33 · 3.14 · 1.331 = 5.57 dm³ ( 1 dm³ = 1 lit. )
V = 5.57 liters
