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
Answer: Step-by-step explanation:
In order to answer this question you will need to find 2 distances and then add them to each other.
Begin at -29. How far will you have to move to the right 29 in order to get to 0?
Now how far will you have to more to get from 0 to 100?
Draw an open number line to help you.
_____________________________________________________
-29 0 100
Your first distance is 29. Your second distance is 100. The total distance is 129.
Answer:
x=4
Step-by-step explanation:
shorter side : longer side = 3 : 7
Equate 3 parts tp 9 inches:
3 parts = 9 inches
Find 1 part:
1 part = 9 ÷ 3 = 3 inches
Find 7 parts:
7 parts = 3 x 7 = 21 inches
Area = Length x Width = 21 x 9 = 189 in²
Answer: The longer side is 21in and the area is 189 in²
