Answer:
Step-by-step explanation:
27π= 120°/360°* πr^2
81=r^2
r=9
Area of circle=πr^2
Area of circle=254.34 or 81π
<u>y = 25</u>
Step-by-step explanation:
<u>=> 115 = y + 90 {exterior angle of triangle is equal to the sum of its opposite two interior angles}</u>
<u>=> 115 = y + 90 </u>
<u>=> 115-90 =y</u>
<u>=> 115 = y + 90</u>
<u>=> 115-90 =</u><u>y</u>
<u>=> y = 25</u>
