Charlie solved an equation, as shown below:
step 1: 5x = 30
step 2: x = 30 – 5
step 3: x = 25
part a: is charlie's solution correct or incorrect? if the solution is incorrect, explain why it is incorrect and show the correct steps to solve the equation. (6 points)
part b: how many solutions will this equation have? (4 points)

256π units²   (answer b)

step-by-step explanation:

the formula for the surface area of a sphere of radius r

is             a = 4πr²

and so, if r = 8 units, then the surface area is:

a = 4π(8 units)² = 256π units²   (answer b)

i think is 3 and 6. this took me 10 min to think.hope to and hope that my answer is brainliest.(follow me )
