3 0

Answer:

16 pi ft^2

Step-by-step explanation:

C = 2 * pi *r

4 pi = 2* pi *r

Divide each side by 2pi

4pi/2pi = 2pi r/2pi

2 = r

We can find the surface area

SA = 4 pi r^2

    = 4 * pi * (2)^2

    = 16 pi ft^2

tresset_1 [31]

Answer:

61 + n = 82

Step-by-step explanation:

So the total number of candy is 82. This is the sum of each type of candy, i.e. 18 + 24 + 19 + n. So we have

18 + 24 + 19 + n = 82

61   +    n            = 82

( if we solve the equation we get n = 82 - 61 = 21)

Hope it helps and if it does please mark me brainliest;)
