The surface area of a sphere is:
A=4πr^2, if r=12 and π is approximated as 3.14 then
A≈4(3.14)(12^2)
A≈4(3.14)(144)
A≈576(3.14)
A≈1808.64 cm^2
Well since there is five people the answer is 40$.

Step-by-step explanation:
A right triangle is formed with the ladder as the hypotenuse. Since the angle made by the ladder with with ground is given, we can use trigonometric functions to solve for the height of the house.
If we let x be the height of the house and using sine function:
sin 24 = x/30
x = 30 sin 24
x = 12.20 ft
Therefore, the house is 12.20 ft tall
