The area of the sector is 86.81π mm²
<u>Explanation:</u>
Given:
Radius of the sector, 25mm
Angle, α = 50°
Area of the sector, A = ?
We know:
Area of the sector = 
On substituting the value, we get:

Therefore, the area of the sector is 86.81π mm²
Answer:
104
Step-by-step explanation:
PEMDAS, do the multiplication first and then the addition
Answer:
-4
Step-by-step explanation:
let n be least.
3n-12=4(n+n+2)
3n-12=8n+8
3n-8n=8+12
-5 n=20
n=-4
Answer:
16 cm
Step-by-step explanation:
Let the width be x
The length will be 3 x since the length is three times the width
Perimeter=2(l+w) where l is length and w is width
By substituting 128 cm for perimeter, x for w and 3 x for l then
128=2(3x+x)
128=8x

Therefore, the width is 16 cm, the width is 16*3=48 cm
There are 36 inches in a yard so 36*2.54 = 91.44 centimeters
