Depending on what you’ve learned make a question about your opinion.

You must use the formula for calculate the surface area of a sphere, which is:
SA=4pir^2
By using the information given in the problem shown above, you have:
SA=4pir^2
r=1 inch
SA=4pi(1 inch)^2
SA=13 in^2
First find the tangent line
dy/dx=2x
at x=6, the slope is 2(6)=12
so
use point slope form
y-y1=m(x-x1)
point is (6,36)
so
y-36=12(x-6)
y-36=12x-72
y=12x-36
alright, so we know they intersect at x=6
and y=12x-36 is below y=x^2
so we do


the area under the curve bounded by the lines and the x axis is 72 square units
The volume of a cone is equal to 1/3•pi•r^2•h. If you want to find the volume of something in terms of pi, you must multiply all other numbers and leave the answer without multiplying the pi in.
In this case, the radius is equivalent to 2mi and the height is equivalent to 7mi. This means….
r^2=4
h=7
Now plug in the numbers into the formula for the volume of a cone.
1/3•4•7•pi
28/3pi
The answer is 28/3 pi.
