A car entered a roundabout from Mason Avenue, traveled 280 feet, then turned onto Perry Street. If the roundabout has a diameter of 150 feet, find the angle of rotation to the nearest degree the car traveled

The angle of rotation is 214°.

Step-by-step explanation:

Formula for arc length:

The length of arc is the product of radius and the central angle ( in radian).

L= rθ

L= Length of arc

r= Radius

θ= Central angle (in radian).

Here L= 280 feet and diameter =150 feet.

Radius feet =75 feet

L= rθ

radian.

We know that,

π  radian= 180°

                      = 214°

The angle of rotation is 214°.

answer: city needs 2.4 inches of rainfall more to match the record of 40 inches.

step-by-step explanation:

since we have given that

total annual rainfall a city record = 40 inches

this year, total rainfall recorded = 37.6 inches

number of inches of rainfall   is needed to match the record of 40 inches is given by

hence, city needs 2.4 inches of rainfall more to match the record of 40 inches.
