The definition of diameter is
distance from the center of any point on the circle
distance across the circle through the center
distance from one point to another
distance around the circle
The definition of circumference is
distance from the center of any point on the circle
distance from one point to another

what is the formula for finding diameter
r = 2 d
d = 2 r
a = m c2
c = π 2 r
what is the formula for finding radius
c = π d
c = 2 π r
d = r/2
r = d/2
what is the formula for finding circumference
select ALL that apply
c = π d
c = 2 π r
d = 2 r
r = d/2
what is the formula for finding area of a circle
C = π r2
A = π r2
A = π r2 / 2
C = 2 π r
what is the diameter of the inner circle
16 in
12 in
4 in
8 ft

Oscar is selling Pringle Chips to raise money for a field trip. The container has a diameter of 9 inches and a height of 32 inches.
Which equation can be used to find the volume of the container?
V = π(9)
V = π(4.5)2(32)
V = π(9)2(32)
V = π(4.5)(32)
