Answer:
v=2πrh
r=d/2=8/2=4
Therefore, V=2×3.142×4×2= 50.272 ans.
Answer:
r=4
Step-by-step explanation:
Area of a circle is
A = pi* r^2
We know the area and 3.14 = pi
50.24 = 3.14 * r^2
Divide each side by 3.14
50.24/3.14 =3.14 /3.14 *r^2
16 = r^2
Take the square root of each side
sqrt(16) = sqrt(r^2)
4 =r
Study. also, i would leave the answer there, but it says i need 20 words to answer so thats why i included this extra bit, but yeah just study.
