Question

Geometry help!!

Answer 1

area of a circle = pi r^2
sector = theta (in rad) *r^2

Answer 2

=30*pi/180 * 12^2

Answer 3

24 pi?

Answer 4

or 75.36

Answer 5

24 pi

Answer 6

thanks! could you help me with a few more?

Answer 7

ok

Answer 9

circle is pi r^2
sector is theta (rad) r^2
pi r^2-theta(rad) r^2
r^2(theta(rad)=pi)

Answer 10

r=16/2
45*pi/180=1/4pi
8^2(pi-1/4pi)=64pi(1-1/4)

Answer 11

3/4*64 pi= 48 pi

Answer 12

so its 48?

Answer 13

48 pi

Answer 14

I only have 2 more after this one.

Answer 15

look at it. is 1/4 of a circle okay

Answer 16

and tringle

Answer 17

so finding the area of 1/4 circle then subtract the triangle

Answer 18

(1/4 pi 8^2)-1/2 *8^2

Answer 19

8^2(1/4pi-1/2)
8^2(pi/4-2/4)=8^2(pi-2)/4

Answer 20

=18.24

Answer 21

Answer 22

the area of a circle - 1/4 of a circle + triangle

Answer 23

the area of a circle = pi r^2, r=18
area of 1/4 a circle =pi r^2/4
area of the triangle = 1/2 b*h = 1/2 18*18

Answer 24

=pi *18^2-pi* 18^2/4+ 1/218^2

Answer 25

=3/4*pi*18^2+1/2*18^2

Answer 26
