We know that the perimeter of a cylinder is 2πr we will find it as we do always. The perimeter will be :
2 pi r
= 2 pi * 20
= 40 pi
Because it says rounded to the nearest tenth the answer will be : 125.6 cm^3
Because we have a half of a cylinder we will just divide the answer we got by 2:
125.6cm^3 /2 =62.8
The answer is 62.8 cm^3

Assoli18 [71]

Answer:

17/7, y = 21 * (17/7), 51

Step-by-step explanation:

so to find what x is, we need to find how much it rises in 1 minute. we do that by dividing 17 by 7. we then see that we want to find how much is it filled in 21 minutes. we then multiply (17/7) by 21 to find the y which is 51

bogdanovich [222]

Answer:

(0,0) is a solution to n=m and n=4m

Step-by-step explanation:

For the first equation, If u insert 0 as m into n=m

n=(0) then n will equal 0.

For the second equation, if u insert 0 as m in n=4m

n=4(0) then n will also equal 0.

So the answer is (0,0) is a solution to n=m and to n=4m

Hope this helps :)
