H = -16t ^2 + 38t + 5.

for rewrite in vertex form is -16(t-19/16)^2 + 441/16

for rewrite in intercept form is h= -16(t-5/2)(t+1/8)

Step-by-step explanation:

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !

just take the area of the square and then the area of the circle then subtract the circle area from the squares area
