What is the length of a diagonal of a cube with a side length of 8 inches? Length of a diagonal of the face:

8 squared + 8 squared = c squared. 64 + 64 = c squared. 128 = c squared. StartRoot 128 EndRoot = c squared.

Use the diagonal of the face of the cube and the side length of the cube to find the length of the diagonal of the cube. Round to the nearest tenth of an inch.

The diagonal through the interior of the cube is about
inches.

what do u need to know

step-by-step explanation:

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.
