It's either 7 and 7 or 7 and 6.86
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
180 degrees - 25 degrees =
A: 155 degrees
*note: 180 degrees total in a triangle
