Answer:
258.3 sq inches
Step-by-step explanation:
Use the sphere surface area formula, SA = 4
r²
The diameter is 9.07 inches, so the radius is 4.535 inches.
Plug in 3.14 as pi and 4.535 as r, and solve:
SA = 4
r²
SA = 4(3.14)(4.535)²
SA = 258.3
So, the surface area is approximately 258.3 sq inches

Answer:
Sally and Kent would have to each work a total of 15 hours to have the same amount of money in their checking account.
Step-by-step explanation:
Set up equations.
x = hours, T = total $
Sally:
T = 200 + 15x
Kent:
T = 245 + 12x
Set both equations equal to each other.
200 + 15x = 245 + 12x (subtract 200 from both sides)
15x = 45 + 12x (subtract 12x from both sides)
3x = 45 (divide both sides by 3)
x = 15
