One inch of rain on a square foot of land weighs 5.2 pounds. About how many gallons of rain are there? Round your answer to the nearest tenth.

this is a problem set. If an inch of rain on a square foot is 5.2 pounds, convert this 5.2 pounds into litres aka. 5 litres. and 20 ml.

if rounding, answer is 5 litres and not 6 litres. bcoz we take the 50s as equator. rounding 20 down to 5 litres.

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
