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

Korolek [52]

Let
x--------------> total volume of a glass

we know that
(4/7)x-70=(2/4)x------------> (4/7)x-70=(1/2)x--------> 2*(4/7)x-2*70=x
(8/7)x-140=x

multiplied by 7 the expresion
7*(8/7)x-7*140=7*x-----------> 8x-980=7x--------> x=980 cm³

the answer is
the total volume of the glass is 980 cm³
