Answer:

half of 20 is 10

10 is your new radius so

10^2 = 100

100 x 3.14 = 314

Now we multiply by the height:

314 x 11 = 3,454 cm^3

Show that the ratios 10/20 and 30/60 from a proportion by finding a common multiplayer. Show that the ratios are equal by writin

Ratling [72]

5 can go into 10 and 20 so you just want to divide them by five which gives you
2/4.

its still not simplified yet so 2 can go in to 2 and 4 so we divide them your answer should be 1/2

so your simplified answer for 10/20 is 1/2

so 10/20=1/2

same thing for 30/60

10 can go into 30 and 60 so we divide them by 10

you should get 3/6

its still not simplified

3 can go into 3/6 so we divide them by 3

you should get 1/2

so 30/60= 1/2

10/20 = 1/2.

30/60 = 1/2

so your simplified answer for both of them is 1/2

I hope this helped!

Modulus: If z1=-2+3i and z2=1+2i calculate, |z1|, |z2|, and |z1+2z2|

marin [14]

$|z_1|=\sqrt{(-2)^2+3^2}=\sqrt{4+9}=\sqrt{13}\\
|z_2|=\sqrt{1^2+2^2}=\sqrt{1+4}=\sqrt{5}\\\\
z_1+2z_2=-2+3i+2(1+2i)=-2+3i+2+4i=7i\\
|z_1+2z_2|=\sqrt{0^2+7^2}=7
