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
Since figure t is twice the size of figure s, figure t would be twice the size of s. hence the answer would be a scale factor of 2.
The answer is 1 3/9. The reason is because it repeats 3 so it would be 9 at the bottom.
