Answer: A
Step-by-step explanation:
The diameter is 10 ft and to get r you divide 10 by 2 to get 5. Then square the radius and multiply by h.
Answer:
R - 15 = 77
R = 77 + 15
R = 92
390.377
pi*r^2
8) 21 milliliters
i am not completly sure but it is NOT the whole
9) .4 & 40%
7) 9670 feet
10) a) $7200 b)350,000
cuz 35% of 60 is 21
cuz 120/300 is .4 and if you take 300 * .4 it equals 120
