1. My uncle is going to dig a cylindrical swimming pool with a bottom diameter of 4 m and a depth of 1.5 m. the side and ground of the swimming pool should be plastered with cement. If the cement is 10 kg per square meter, how many kg of cement will be used? 2. There is a cone-shaped wheat pile with a total weight of 3717.76kg. It is known that the radius of the bottom of the pile is 2m. If the weight of each cubic meter of wheat is about 740kg, the height of the pile can be calculated

I'm glad to help you
The first formula is 3.14 * 2 ^ 2 + 2 * 3.14 * 2 * 1.5
The second formula 3717.76 / (3.14 * 2 ^ 2 * 740)
I hope I can help you
