Answer:
A
Step-by-step explanation:
Answer:
I think it is 37.5°.
Step-by-step explanation:
The formula for a cone is given as:
<span>V = π r^2 h / 3 --->
1</span>
Where,
V = volume of the cone
r = radius of the circle base of the cone
h = is the perpendicular length from the center of the
base of the cone to the tip at the top
It was given that:
h = d
but d = 2 r, therefore:
h = 2 r
Substituting this to equation 1:
<span>V = π r^2 (2 r) / 3 </span>
V = 2 π r^3 / 3
Since r = x, the answer from the choices is:
<span>2πx3</span>
