Answer:
≈ 4.89
Step-by-step explanation:
A = πr²
75 = 3.14 x r²
r² = 75 / 3.14 = 23.89
r = 4.89
Find the volume of the cylinder and divide by 2:
V = pi * r^2 * h
V = 3.14 * 11^2 * 17
V = 6458.98
Divide by 2 since it's half full:
6458.98 / 2 = 3229.49
Now divide it by 46.2 to see how long it will take to drain out:
3229.49 / 46.2 = 69.902
So it will take approximately 70 seconds to drain out.
Answer:
Peter's number is 36.
Step-by-step explanation:
If you subtratct 13 from 36, you get 23.
If you multiply that times -3, you get -69.
(The way I got 23 was by dividing -69 and -3)
I hope this helped you even though it's late.
4/1 is the same as 4.
So 4+3/4= 4 and 3/4
<u>Final Answer</u>= 4 and 3/4
3.5 pound = 3 5/10 pounds = 3 1/2 pounds
Now, 1 pound = 16 ounces, so 1/2 pound = 16*1/2 = 8 oz
<span>So the answer is 3 pounds and 8 oz.</span>
