What is the exact area of a circle having radius 7 in.?

Soo to get the are you need to follow the formula
Area= pi multiplied by radius (squared)
I don't have the right symbols sorry. Anyways let's continue
First multiply pi which is 3.14 then multiply it to the radius, since the radius is squared then you have to multiply it twice

Solution:
Pi(3.14)xradius that is squared (7 raised to the power of two)
3.14 x 7 x 7= 153.86

Step-by-step explanation:

Since, circle of center (-3 , -2) is passing through the points (0 , -6) and (a , 0).

Therefore, points (0 , -6) and (a , 0) will be equidistant from the center of the circle (-3 , -2).

Hence,

Distance between (0 , -6) and (-3 , -2) = Distance between (a , 0) and (-3 , -2).
