Find the area of center C . Round your answer to the nearest hundredth. A circle with center C and a chord with point C on chord. The length of chord is 20 inches.

The area is about ??? square inches.

ok then what happened.

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.

- (2, -7)

- lines r and s and lines t and u must be parallel

113.1

step-by-step explanation:

v=4

3πr3=4

3·π·33≈113.09734
