Answer:
3391.2
Step-by-step explanation:
The formula for the volume of a cylinder is
pi * r^2 * h
Plugging the values in we get
3.14 * 6^2 * 30
= 3.14 * 36 * 30
= 3391.2
Answer:
4t^2-32t+64=4(t^2-8x+16)
Step-by-step explanation:
f(x)=4x^2-8x+4
f(t-3)=4(t-3)^2 - 8(t-3)+4=
4(t^2-2*t*3+9)-8t+24+4=
4(t^2-6t+9)-8t+28=
4t^2-24t+36-8t+28=
4t^2-32t+64=4(t^2-8x+16)
C=2πr=2·π·1≈6.28319
so the answer is 6.28
