Answer:
Step-by-step explanation:
Hey
So we are given circumference as 81.681.64m
Formulae for circumference is 2 pi r
When you substitute 2(3.14)r= 81.64m
R = 13m
Area of the horizontal cross section is just the circle above the cylinder and the formulae is pi r^2
So it will be 3.14(13)^2
To give you 530.66m^2
Hope this helped
