Maria’s family painted the outside of her house. They bought paint in a bucket with a radius of 15.0 cm and a height of 35.0 cm. Because the bucket was so heavy, they poured the paint into cans that have a radius of 10.0 cm and a height of 20.0 cm. How many cans did they need?

Step-by-step explanation:
Volume of the bucket=v1=pi×r^2×h
=22/7×225×35
=24750 ccm
Volume of the cans=v2=22/7×100×20
=6280(approx)
No. Of cans=v1/v2=24750/6280=3.9...=4 approx
