Answer: X = 20
Step-by-step explanation:
7x - 99 = 2x + 1 --Take 2x from both sides
-2x -2x
5x - 99 = 1 -- add 99 to both
+99 +99
5x = 100 --Divide by 5
÷5 ÷5
x = 20
The formula you use to find the surface area of a sphere is A=4 π r^2
4×π = 12.5663706143
r = 4
4^2 = 16
12.5663706143 × 16 = 201.061929829
Final answer: the surface area is about 201 ft.
