In this question, it is given that the base radius is 2 , height is 6 and the value of pi is 3.14 .
And we have to find the volume of the cylinder, and for that, we have to use the following formula

Substituting the values of pi,r and h, we will get

Answer:
Probably 10
Step-by-step explanation:
10/5=2
I believe you combine the first and last terms first because they have the same denominator
<h2>63.6 cm</h2><h2 />
Cut diameter in half to find radius
9/2 = 4.5
radius = 4.5
This is the formula for area of a circle:
pi * radius^2
pi * 4.5^2
20.25pi
Now find pi:
20.25 * pi = 63.6
Answer:
63.6 cm is the area
Hello! So, the train travels 80 miles in an hour. 90 minutes is equivalent ot 1 ½ hours. In case you don't know, ½ of 80 is 40. To find the distance gone in 90 minutes, we can just add 80 and 40. 80 + 40 is 120. Another way to solve it is to multiply 80 by 1.5 and you would still get the same answer. There. The train will have gone 120 miles in 90 minutes.
