, which is our answer.
A cross section is a shape formed by cutting an object using a plane. For this case, a cone is sliced parallel to the slant height so the cross section formed would be a plane with a U-like shape. From the image attached, the correct answer is the second option.
15/ 100
To simplify divide both by 5
15/100 / 5 = 3/20
Hey there! :D
Area= πr^2
So, the radius is half the diameter.
14/2= 7
7^2= 49
49π <== the answer
I hope this helps!
