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.
33 c = 91.4 Fahrenheit
62 c =143.6 f
-25 c= -13 f
89c= 192.2 f
212c = 413.6 f
Answer:
11%/ 0.11
Step-by-step explanation:
I=prt
154=700*x*2
154=1400x
divide 1400 by both sides
=0.11
or 11%
We have to write

In log form
To convert exponential equation to log equation, we have to use the following rule
So we will get

or

And that's the required log form .
