The arc measurement of the sector is 216°.
Therefore the area of the sector is 216/360 = 0.6 of the area of the entire circle.
Let r = the radius of the circle.
Then the area of the circle is πr².
Therefore the area of the sector is
0.6*πr²
Because the area of the sector is 15π cm², therefore
0.6πr² = 15π
r² = 15/0.6 = 25
r = 5 cm
Answer: 5 cm

Step-by-step explanation:
-5 is the coefficient in the term -5y
The number which is multiplied with the variable is called the coefficient of the variable
77% of the school want electronic newsletters, so 23% of the school want physical paper newsletters.
77% of 650 is 500.5.
23% of 650 is 149.5.
650/100 = 6.5
6.5x77 = 500.5
6.5x23 = 149.5
It's best to round that figure up to 150 as there will not be a parent who only needs half of the newsletter.
