Question

An office water cooler has a height of 1.7 feet and a base diameter of one foot. About how many gallons of water does the water cooler bottle contain if 1ft=7.5 gallons?

Answer 1

10 gallons

Explanation:

This question is on volume and capacity

The volume of a cylinder is given by, v=
`\pi`r²h

where r is the radius and h is the height

h=1.7 feet and r=0.5 feet

v= 3.142×0.5×0.5×1.7

v=1.335 ft³

given that 1ft³=7.5 gallons

then 1.335 ft³=?

perform cross multiplication⇒(1.335×7.5)÷1 =10.01

=10 gallons
