The radius is 5 inches, so r = 5
The height is 30 inches, so h = 30
We'll use pi = 3.14

Plug in the given values and then use PEMDAS to simplify
SA = Surface Area
SA = 2*pi*r^2 + 2*pi*r*h
SA = 2*3.14*5^2 + 2*3.14*5*30
SA = 2*3.14*25 + 2*3.14*5*30
SA = 6.28*25 + 6.28*150
SA = 157 + 942
SA = 1099

Answer: 1099

Write the ratios for sin C, cos C, and tan C.

rosijanka [135]

Answer:

sin C = 7/25

cos C = 24/25

tan C = 7/24

Step-by-step explanation:

opposite of C = 7

adjacent of C = 24

hypotenuse of C = 25

sin = opposite / hypotenuse

so sin C = 7/25

cos C = adjacent / hypotenuse

so cos C = 24/25

tan = opposite / adjacent

so tan C = 7/24
