Answer:

Step-by-step explanation:
If the angle θ is in radians, the formula for the area (A) of a sector of a circle is
A = ½r²θ
If θ is in degrees

Data:
θ = 49°
r = 11 cm
Calculation:

30% is 24
45% is 36
take 15% and multiply it by however much it takes to make the percentage than multiply that by 12
For 27,the temp and time increase
