Answer:
The radius is 5 in
Step-by-step explanation:
The area of a circle is given by the formula
A = pi *r^2
We know the area = 78.5 in^2 (volume would be in^3 area is in^2)
78.5 = 3.14*r^2
Divide each side by 3.14
78.5/3.14 = 3.14/3.14*r^2
25 = r^2
Take the square root of each side
sqrt(25) sqrt(r^2)
5 =r
Answer:
x=-24 is the correct answer
How do you know the answer if you don't have the work?
2/3(x+1/8) =1/6(x)
2/3×x+2/3×1/8=1/6(x)
2/3(x)+1/12=1/6(x)
2/3(x)-2/3(x)+1/12=1/6(x)-2/3(x)
1/12=1/6(x)-2/3(x)
1/12=1/6(x)-4/6(x)
1/12=-3/6(x)
1/12÷-3/6=-3/6(x)÷-3/6
-1/6=x
Its 2 11/12 hope it helps
