Answer:
Step-by-step explanation:
Area of circle = 78.5 in²
πr² = 78.5
3.14*r² = 78.5
r = 5 in
Answer:
if the diameter of the circle is 25, then the radius will be 12.5.
A=3.14(12.5)2 --> 490.9m^2
C= 2*3.14(12.5)---> 78.5 m
3. 28 Quarters and 5 dimes.
8:2
divide each side by 2
4:1
For every _8_ books sold there were _2_ movies sold OR
For every _4_ books sold there were _1_ movies sold
C. 15a+100
This is a binomial
