B. 31.4 (pi) units

C. 31.4 units

A. 10 (pi)

Explanation:

Well since the equation to find circumference is C = 2(pi)r

And 10(pi) is exactly 2(pi)r, it’s not the answer.

And if we use 3.14 as an estimate for (pi), then 31.4 is also true for the circumference, because 10•3.14=31.4.

Also 10(pi) is more acurate then 31.4 because (pi) isnt exactly 3.14 its more like 3.1415926535...

Hope this Helps!

Please help me ASAP, thank you ^-^. The radius of the cone is 7 in and y = 25 in. What is the volume of the cone in terms of π?
MrRa [10]
<h2>Answer:</h2>

The volume of the cone in terms of π is:

             

A.     392π in³

<h2>Step-by-step explanation:</h2>

The radius of the cone i.e. r is: 7 in.

and the slant height of the cone i.e. l=y=25 in.

and let h=x be the height of the cone.

Now, using the Pythagorean Theorem we have:

l^2=r^2+h^2\\\\i.e.\\\\h^2=l^2-r^2\\\\i.e.\\\\h^2=(25)^2-7^2\\\\i.e.\\\\h^2=625-49\\\\i.e.\\\\h^2=576\\\\i.e.\\\\h=\sqrt{576}\\\\i.e.\\\\h=24

Hence, we get:

h=x=25\ in.

Now, the volume of the cone is given by:

Volume=\dfrac{1}{3}\pi r^2h\\\\i.e.\\\\Volume=\dfrac{1}{3}\times\pi\times (7)^2\times 24\\\\i.e.\\\\Volume=392\pi\ in^3

        Hence, the answer is: Option: A
