Answer:
The diameter of the circle is 24.9 in
Explanation:
To solve this exercise we need to use the circumference formula of a circle and clear d:
c = circumference = 78.1 in
d = diameter
π = 3.14
c = π * d
d = c / π
we replace the known values
d = 78.1 in / 3.14
d = 24.8726 in
round to the nearest tenth
d = 24.8726 in = 24.9 in
The diameter of the circle is 24.9 in
