Answer:
1/5
Step-by-step explanation:
Answer: 2π ft^2
Step-by-step explanation:
Area of a circle= π x the radius ^2
here your diameter is 4, and the radius is equivalent to half of the diameter so your radius equals 2.
A= π x 2^2
The surface area of a sphere is...
A = 4 pi r^2
We would find the radius in which we make this an equation of the radius.
r = (sqrt A pi) / 2 pi
Once we identify r we would then input the radius in the equation for the volume of a sphere....
<span>V = 4/3 pi r^3</span>
The scientific notation is <span>4.21 x 10/<span>8
