In the derivation of the formula for the volume of a cone, the volume of the cone is calculated to be times the volume of the pyramid that it fits inside. which statement best describes where the comes from in the formula derivation? it is the ratio of the area of the square to the area of the circle from a cross section. it is the ratio of the area of the circle to the area of the square from a cross section. it is the difference of the area of the square and the area of the circle from a cross section. it is the sum of the area of the square and the area of the circle from a cross section

step-by-step explanation:

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2

the domain of a function is the set of input values, x , for which a function is defined. the domain is shown in the left oval in the picture below. the function provides an output value, f(x) , for each member of the domain.

so the possibilities of the measurement of the side of the triangle are either it is longest side or not the longest side

when it is the longest side

s < 25 + 35s < 60

if it is not the longest side

35 < 25 + s10 < sso 10 < s < 60so the perimeter70 < p < 130
