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>
Answer:

Step-by-step explanation:
Number of points scored by River = 
Number of points scored by Paul = 
River has scored 15% more points that Paul.
To find:
Equation to represent the given condition.
Solution:
As per the given question statement, Number of points scored by River is 15% more than that of Paul's.
15% of points scored by Paul = 15% of
= 
15% more means total points scored by Paul plus 15% of points scored by Paul.
Therefore, we can write the following:

Answer:
b. divide each side by 4.75
Step-by-step explanation:
4.75x = 24.7
divide each side by 4.75
x = 5.2
check your work
4.75(5.2) = 24.7
24.7 = 24.7
