Answer:r=20 cubic inches

Step-by-step explanation: Looking at this question critically and solving it mathematically, then we are going to say the volume of cylinder is πr^2h

V=15072 cubic inches r=? H=12cubic inches

15072cubic inches=3.14×r^2×12cubic inches

15072cubic inches=37.68 cubic incher^2

r^=400

We are going to take square of both sides, and our answer will now be

r=20 cubic inches

Vinil7 [7]

Answer:

250 ft

Step-by-step explanation:

circumference of circle 'C' is defined as

C = 2πr

250π = 2πr

r = 250π/2π

r= 125

d = 2r = 2×125 = 250 .

Pls help just please will mark BRAINLIEST
Darina [25.2K]

Answer:

44.2545

Step-by-step explanation:

you can find the third angle by taking 180-(90+55)=a

a=35

use law of sines

Sin(angle)/(opposite side of angle)=Sin(another angle)/(opposite side of another angle)

so, sin(a)/A=sin(b)/B

sin(35)/33=sin(55)/x

x=sin(55)/(sin(35)/33)

x=44.2545

Hope this helps :)
