Answer:
154
Step-by-step explanation:
The formula for the area is A=πr2
The line labeled 7 is the radium or the R in the formula
Replace 7 with R
A=π7(squared)
square seven
A=49π
pi is approximately 3.14
mutiply 7 by pi
A= 154
Answer:
65° and 115°
Step-by-step explanation:
Supplementary angles add up to 180
So if you add A and B you get 180°
x + 50 + x + 100 = 180
2x + 150 = 180
2x = 30
x = 15
A = 15 + 50
A = 65
B = 15 + 100
B = 115
