Answer:

2,553.8 cc

Step-by-step explanation:

Use the volume-of-a-cylinder formula:  V = (base area)(height).

Since the round base of the cylinder has area A = πr², and since r = 8.3 cm and (height) is 11.8 cm, the volume of this cylinder is

V = πr²h = π(8.3 cm)²(11.8 cm) = 2,553.8 cc

Question 2:
Helga [31]

Answer:

15mins

Step-by-step explanation:

Given that he worked out a total of 360mins, and jogged 45mins/day:

Jog \ Time=Total \ Time- Bike \ Time\\=360-(45\times6)\\=90min

Therefore, Allen jogged a total of 90mins in the past one week. To calculate the time jogged each day, we divide the total jog time by number of days jogged:

t_d=Total \Time/(No \of \ Days)\\=90/6\\=15mins

Allen jogged 15mins per day.

Arte-miy333 [17]
There are 17 action movies because when we divide 20 by 100 the answer we get which is 0.2 is the amount of movie for 1% so we then multiply 0.2 by 85 to get the amount of movie for 85% which is 17 action movies. I hope my explanation was clear.
