The area of a circle is found by pi*r^2

We can plug in the values we know to solve for the radius.

12.56 = 3.14*r^2

Divide both sides by pi.

12.56/3.14 = r^2

Square root both sides.

r = 2 yards

The diameter of a circle is twice as long as the radius, so the answer is 4 yards.

Estimate a 15% tip on a taxi ride that cost $23.25
Anettt [7]
So basically, we are looking for the amount of tip that the rider gave the driver if the driver paid a total of 23.25 dollars. So in order to get the tip, we just have to multiply the total cost of the taxi, which is 23.25, to the percentage of the tip which is 15%. So in order to get the final answer, we have to express the formula as this. 23.25 x 0.15. So if we would solve this equation, we will get an answer of 3.4875. So the tip that was given was 3.4875
