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

D-StartFraction pi Over 4 EndFraction(StartFraction 4 r squared h Over 3 EndFraction)

Step-by-step explanation:

It is the ratio of the area of the circle to the area of the square from a cross section.

intensity of the vector is v= √37 ≈ 6.08 units and make angle ∡α ≈ 9.46° with east direction

step-by-step explanation:

required vector is consists of the two componentsvx= 2+4=6 units   and vy= 1 unit and vx ⊥ vywe will use pythagorian theorem to find intensity of the vector vv∧2 = vx∧2 + vy∧2 => v = √vx∧2 + vy∧2 = √6∧2 + 1∧2 = √36+1 = √37 ≈ 6.08 unitsthe angle ∡α between vector and east direction we wil find with tanαtanα = 1/6 => α = arc tanα = arc 1/6 => α ≈ 9.46°

hope this
