Answer:
Step-by-step explanation:
In order to find the area of a circle we multiply π by the radius, and to find the radius of a circle we have to look at the line that stops directly in the middle of the circle.
Once we then have the radius, we simply multiply the radius, (with an exponent of 2) by π and then we will have our answer. Of course, round if needed.
Hope this helps.
The answer is B.
Hope that helps, if you need any more help, just ask : )
ANSWER: The expression that represents the volume of the cone written in terms of π is: 18π in^3
First thing is that you need to find the diagonal of the rectangle
but remember is it a horizontal rectangle.
So let's start it :)
d= √6²+3²
d= √36+9
d= √54
d= 6.7082
But wait.. we are not done yet
We need to solve KT
we have 6.7082 which is the base and we have SL=4 which is the height
so with this 2 information we can find KT
KT is the hypotenuse because when you draw the line from K to T you'll see that it is the longest line.
Use the hypotenuse formula which is
C = √a²+b²
Now replace C by KT since we are solving for KT instead of C. Got it ?:)
KT= √6.7080²+4²
KT= 7.81
I do it with decimals so it might be little bit confusing to you but I think you can solve that different ways :)
Well I hope that's help and if not I am so sorry.
