Answer:
37.5 V
Step-by-step explanation:
A p e x : )
V(cylinder)= πr²h
d=2r,
d is diameter, r is radius.
When diameter is tripled, a new diameter D=3d,
new radius R=3d/2=(3*2r)/2=3r
R=3r
V(new cylinder)= πR²h = π(3r)²h=9πr²h
V(new cylinder)/V(cylinder)=9πr²h/πr²h=9
Volume new cylinder 9 times more the volume of old cylinder.
Answer:
Step-by-step explanation:
1. Answer below
![2x = \sqrt[3]{125}](https://tex.z-dn.net/?f=2x%20%3D%20%5Csqrt%5B3%5D%7B125%7D)



2. Answer below
![x + 3^{2} = \sqrt[3]{27}](https://tex.z-dn.net/?f=x%20%2B%203%5E%7B2%7D%20%3D%20%5Csqrt%5B3%5D%7B27%7D)


Y= 32 if x= 8, 2 times 16 is 32
