The diameter of the moon is approximately one fourth of the diameter of the earth. Find the ratio of their surface areas

Step-by-step explanation:

Area of a sphere is

let d be the diameter of the moon and D be the diameter of the earth

d = 1/4 D

Area of Earth =

Area of moon =

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
