C=2πr
We have 3/4 of circumference
(3π/2)*2π=3/4.
and it is equal 5π/2.
(3/4)*C=(3/4)*2πr
5π/2 = 6πr/4
5/2=6r/4
r=(5/2)*(4/6)=(5*4)/(2*6)=5/3
r=5/3
Answer:
8 dollars
Step-by-step explanation:
We can write a ratio to solve
15 stickers 12 stickers
------------------ = ----------------------
10 dollars x dollars
Using cross products
15 *x = 12 * 10
15x = 120
Divide each side by 15
15x/15 = 120/15
x =8
8 dollars
5 1/6 * (-2/5) = __
turn 5 1/6 into a mixed fraction
31/6 * (-2/5) = __
multiply
31 * -2 = -62
6 * 5 = 30
so -62/30 or -2 1/15
