3(9+5n)
Use the distributive property to multiply 9 by 3 and 3 by 5n to get that answer.
The circumference of a circle is 2πr
32π:2πr=240:360
16:r=2:3
2r=48
r=24
<h2><u>Answer:</u></h2>
The Volume of a cylinder is calculated by the following formula (equation 1):
(1)
Where is the radius of the circle that is the base of the cylinder and the height.
If we divide equation (1) by we obtain the area of the circle, as shown in equation (2):
(2)
Now, we know the volume of the cylinder in this problem is expressed as:
(3)
And its height as:
(4)
Knowing this, let’s find the area of the base (area of a circle):
If we divide each term by the common denominator we have:
Simplifying we finally have:
>>>>> This is the expression of the area of the base
