Answer:
14.13 in³
Step-by-step explanation:
Volume of a ball (sphere) is:
V = ⁴/₃ π r³
Circumference of a ball (circle) is:
C = 2π r
Use the circumference to find the radius.
9.42 in = 2π r
r = 1.50 in
Use the radius to find the volume:
V = ⁴/₃ π (1.50 in)³
V = 14.13 in³
Answer:
50.29 cm
Step-by-step explanation:
Given:
Diameter of each doughnut = 8 cm
To find: circumference of each doughnut
Solution:
Circumference refers to the boundary of a geometric figure.
A doughnut has the shape of a circle.
Let r represents the radius of the circle.
Diameter of each doughnut = 8 cm
Radius of each doughnut (r) = Diameter/2

Circumference of each doughnut 
Put 
So, circumference =
