Answer:

r = 4.24 inches

Step-by-step explanation:

Given that,

The surface area of the ball, A = 226.8 sq inches

The formula for the surface area of a sphere is given by :

$A=4\pi r^2$

Where

r is the radius of the ball

$r=\sqrt{\dfrac{A}{4\pi}} \\\\r=\sqrt{\dfrac{226.8}{4\pi}} \\\\r=4.24\ inch$

So, the radius of the ball is 4.24 inches.

For the equation 4(2x-4)=8x+k, what value of K will create an equation with infinitely many solutions? Please show steps

strojnjashka [21]

If you use the distributive property, you will multiply 4 by 2x to get 8x and 4 by -4 to get -16.

8x-16=8x+k

If you want infinitely many solutions the equations on both sides of the equal sign need to be the same. So, k would need to be -16.
