Answer this please .

Total surface area is 48 the lateral surface area would be 36

Step-by-step explanation:

4 x 3 = 12

Half of 3 (1.5) x 4 = 6 which you do twice so 12

5 x 3 = 15

3 x 3 = 9

Add all that and you get 48

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.
