Answer 2

A=πr^2 is area for circle

Answer 3

so \[15^2\] is what

Answer 4

225

Answer 5

so what is your answer?

Answer 6

225π yd2

Answer 7

yup :)

Answer 8

thank you

Answer 9

no problem

Answer 10

medal me :)

Answer 11

and close the problem

Answer 12

*please*

Answer 13

okay

Answer 14

225 PI square yards is wrong
area of a circle = PI*radius*radius
area of a circle = PI*15*15
area of a circle = PI * 225 IF we needed the area for the entire circle.
We need the SECTOR area which is 30 degrees of the entire circle.
SO the SECTOR area = 30/360 degrees of the circle or (1/12) of the area
SECTOR area = PI*225*(1/12)
SECTOR area = PI*18.75
The answer is C

Answer 15

okay thank you so much
