Answer 1

Answer:

The formula for volume of a cylinder is pi(r^2)h

Radius is diameter/2 = 15cm/2=7.5 cm

Volume is now (7.5cm)^2 (pi)(84cm).

This volume is in cm^3 and 1cm^3=1mL,

so we can replace cm^3 with mL.

Now divide that by a thousand to find the volume in liters because 1L = 1000 mL

Answer is (7.5cm)^2 (pi)(84cm) * (1 mL / 1 cm^3)* (1L / 1000 mL)

Step-by-step explanation:

This is the answer..
