Multiply 1.75 with 25 because you bought snacks everyday and then you’re left with 11.25

Now subtract .20 because you were left with that on day 26 and you get 11.05

Lastly you divide 11.05 with .85 to see how many snacks you bought

A silo is constructed using a cylinder with a hemisphere on top. The circumference of the hemisphere and the circumference of th

givi [52]

1. The surface that will be exposed to the rain is the lateral surface of the cylinder and the hemisphere.

2. The lateral area of the cylinder is a rectangle with height equal to the height of the cylinder and width equal to the circumference of the base of the cylinder.

3. the circumference of the base = 2 $\pi$ r=2* $\pi$ *5=10 $\pi$
so the lateral area = 10 $\pi$ *h=10 $\pi$ *40=400 $\pi$ ( $ft^{2}$ )

4. The surface area of a sphere is $4 \pi r^{2}$
so the surface of the hemisphere = $\frac{1}{2} *4 \pi r^{2}=2 \pi (5)^{2}=50 \pi$ ( $ft^{2}$ )

5. Total area exposed = 450 $\pi$ $ft^{2}$
