Well, we should start by listing the factors
1,2,3,4,6,8,9,12,16,24,36,72
You can put these in pairs if it will help you,
1*72 2*36 3*24 4*16 6*12 8*9
If you look, you can see that in only one pair the length is twice the width.
So your answer is
W=6
L=12
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:
he bought three math books and four english books
Step-by-step explanation:
26x3=78 (three books)
28x4=112 (four books)
112+78=190
