The greatest common factor is 2
Answer:
The closest measurement is 15.7
Step-by-step explanation:
The formula for circumference is 
The diameter is double the radius, so to get the radius we divide by 2.
5 divided by 2 is 2.5
Knowing "r" is 2.5 we can plug that into our equation and solve.
2 ·
· 2.5 ≈ 15.71
The closest measurement is 15.7
Answer:
The second one because q goes with y r goes with z and s goes with x
Step-by-step explanation:
Area of the sector = 1/2 * r^2 * theta where theta is the angle subtended by the arc at the center ( in radians)
In this case m < theta = 360 - 235 = 125 degrees or 2.182 radians
So, the area of shaded area = 1/2 * 20^2 * 2.182 = 436.4 in^2
