Trick question: The largest piece is the entire cone.
First lets identify the equation for volume.
V= 1/3 h pi r^2
h=45
r=15
V= 1/3 45 * pi 15^2
v= 15* pi 225
3375 pi
You keep pi because the answer has pi.
Answer:
c
Step-by-step explanation:
I'm pretty sure it's asking for the circumference. The formula for finding the circumferene is C=πd (d=diameter) First, you need to fiind the diameter. Thequestion gives you the radius, 6.5, which is half the diameter. multiply that by 2 and you get 13. The question says to use 3.14 as π, so just multiply 3.14 by 13 and you get 40.82, which rounds to 41.
