A car's rear windshield wiper rotates 140°. The total length of the wiper mechanism is 24 inches and the length of the wiper bla
Verizon [17]

Answer:

<h2>312.7 in^2</h2>

Step-by-step explanation:

This problem is on the mensuration of flat shapes, sectors and arc.

we know that the area of a sector is given as

A=(∅/360)*πr^2

Given that the length of the wiper R=24 in

and the length of the blade r= 16in

To find the area of the wiped surface we only require the length of the blade as the radius

The area of the wiped surface is given as= (140/360)*3.142*16^2

A= 0.3888*3.142*256

A=312.7 in^2

Write repeating decimal as a fraction 0.2045454545
Mkey [24]
First, we need to move the decimal point directly in front of the repeating part. To do this, we need to move it two places to the right, which we can do by multiplying by 100.

100 × 0.2045454545 = 20.45454545

Now we need to subtract our original number.

\ 20.454545...\\\underline{-0.204545...}\\20.25

Now we put that over 99 (that's one less than our 100 from earlier)

\frac{20.25}{99}

Our fraction is shaping up, but we shouldn't have a decimal in there. Let's multiply the top and bottom by 100 to get rid of it.

\frac{2025}{9900}

We're going to have to do some simplifying. (the top and bottom are both clearly divisible by 5 and then some)

\frac{2025}{9900}=\frac{405}{1980}=\frac{81}{396}=\frac{27}{132}=\boxed{\frac{9}{44}} <em> done!</em>
