Answer:
153.86
Step-by-step explanation:
In the formula A= pi*r^2, we need the radius of the circle, but we do not have it. To find the radius of a circle, you will divide the diameter by 2.
14/2=7.
Now that we know that the radius is 7, we can fill in our measurements into the formula and find our answer.
A= 3.14(7^2)
A=3.14(49)
A= 153.86
The area of the circle is 153.86 cm^2.

Answer:
24
Step-by-step explanation:
So, first subtract 105-28=77
Now simplify the ratio given. 105:90=21:18=7:6
So she has 77:90 right now. You want it to be 77:66 to fit the ratio.
