Find the radius!
Surface Area = 1,139.82 yd?
radius =
13 yd
O
12 yd
O 11yd

10 yd

11 yd

Step-by-step explanation:

SA = 3r²

1139.82 = 3 × 22/7 × r²

r² = 1139.82/66 × 7

r² = 120.81

r = 10.99 = 11 yd

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
