<span>A 15° sector in a circle has an area of 11.9 m2. What is the area of the circle?
The area of the circle will be found as follows:
the fraction of the sector=15/360=1/24
the area of the circle will be:
area=(fraction of the circle)/(fraction of the sector)*(area of the sector)
=1/(1/24)</span>×11.9
=285.6 m²
The answer is 3.00-0.22=2.78
Answer:
x=29/11
Step-by-step explanation:
7(5x+12)=2x-3
=35x+84=2x-3
=35x-2x=-3-84
=33x=-87
then divide both side by 33
