Answer:
502.4 in²
Step-by-step explanation:
Area of a sphere = 4 πr²
Plastic beach balls are spherical in shape.
Hence, the Area of a sphere = 4πr²
Where r = radius = 2 inches
π = 3.14
Hence, the area of one spherical ball =
4 × 3.14 × 2²
= 50.24 square Inches
For 1 spherical ball, 50.24 square inches of plastic is needed to make it.
How many square inches of plastic does the company need to make 10 beach balls?
Therefore,
1 spherical ball = 50.24 in²
10 spherical balls = x
Cross Multiply
x = 10 × 50.24 in²
x = 502.4 in²
Therefore, 502.4 square inches of plastic is needed by the company to make 10 beach balls.
Answer:
2x
Step-by-step explanation:
when the base is the same, we subtract when dividing, so
3-2=1, 2x^1=2x
Answer:
80x
Step-by-step explanation:
There is no substitution for the variable so the expression is 80x
