Answer:
The diameter of the circle is 24.9 in
Step-by-step 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
The square root of 144 is 12. So multiply 8.3333 by 12. You should get 99.9996.

Rounded -> $29.50
I'm assuming 2 decimal places; would be $29.50.
Answer:
573440 kg
Step-by-step explanation:
Given,
Density of copper ( D ) = 8960 kg / m³
Length of cube ( l ) = 4 meters
To find : Mass of solid cube of copper ( m )
Formula : -
Volume of cube = l³
Volume of cube
= l³
= 4³
= 4 x 4 x 4
= 64 meter³
So,
V = 64 meter³
Formula : -
D = m / V
m = D x V
= 8960 x 64
m = 573440 kg
Hence,
The mass of a solid cube of copper is <u>573440</u> kg.
