Answer:
Perimeter of sector is 47.93 cm which is greater than 47.5 cm
Step-by-step explanation:
Mathematically, the perimeter of a sector is length of the arc plus 2 radii
The length of the arc is;
theta/360 * 2 * pi * r
where theta is the angle subtended by the arc at the center of the circle
Thus, we have
135/360 * 2 * 22/7 * 11 = 25.93
Add 2 radii = 25.93 + 2(11) = 47.93 cm
This is greater than what we are asked to calculate and thus we have shown what we are asked to show
13.7 is 100% I like to divide by 100 to get the 1%, then multiply by the percent i am trying to find, lets see if I'm right.
13.7/10 = .137
.137= 1/100
.137 x 160 = 21.92
Your answer is 21.92, 21.92 is 160%
Hope this helped!

Answer:
The work space in Elisha's room has a width of 1/2 meter and an area of 3/5 square meter. How long is it?
Step-by-step explanation:
In this, width of the room is given and the area is given. We have to find the length.
To find the length, area should be divided by width.
ie. 3/5 divided by 1/2
First you would subtract 30 from both sides
they divide each side by 5 to get -7
y =-7
