Answer 1

Explanation:

9 cause you have to times

Answer 2

The radius of the circle is 9 in

Choice C is correct

Explanation:

254.4696 square inches. Whats the radius of the circle (use pie=3.1416.

The area of a circle with radius r is given as;

`A=\pi *r^(2)`

We substitute the given area and the value of pi given to solve for the radius;

`254.4696=3.1416*r^(2)\\\\r^(2)=(254.4696)/(3.1416)\\\\r^(2)=81\\\\r=√(81)=9\\\\r=9`
