Answer:
Step-by-step explanation:
let x be the number
6+1/5x=12
1/5x=12-6
1/5x=6
x=5*6
x=30
check: 6+(1/5*30)=6+6=12
Answer:
Step-by-step explanation:
Area is pi times r squared. I don't know how to write that on the keyboard. Take your pi(3.142) times the radius(6.2)squared. Pemdas tell us to do exponents first, so 6.2 squared is 38.44. To square a number, just multiply it times itself. So now, we have pi(3.142) times the squared radius(38.44). So, 3.142X38.44=
120.778 Second place is seven followed by eight. Round up. 120.78
I hope you don't find the solution too messy. If there is anything you don't get. Let me know and I will explain it:
Volume of cylinder is 3 times of volume of cone having same base diameter and same height.
<u>Solution:</u>
Given that
A cylinder and A cone have the same diameter = 10 inches and same height = 12 inches
Need to find the relationship between volume of cylinder and cone.
Let’s calculate volume of each object separately first.
<em><u>Calculation of volume of cylinder :</u></em>
Formula of volume of cylinder is given as:

Where π=3.14

height h = 12 inches
On substituting given values in formula of cylinder we get

<em><u>Calculation of volume of cone:</u></em>
Formula of volume of cone is given as:

Here π=3.14

On substituting given values in formula of cone we get


On comparing the two volumes we get

Hence can conclude that Volume of cylinder is 3 times of volume of cone having same base diameter and same height.
