Answer:
100.48 cm³
Step-by-step explanation:
Volume of a cone, V = 1/3 * pi * r² * h
Radius, r = 4 cm ; h = 6cm
V = 1/3 * 3.14 * 4² * 6
V = 1/3 * 3.14 * 16 * 6
V = 3.14 * 16 * 2
V = 3.14 * 32
V = 100.48 cm³
Hence, the volume of the cone is 100.48 cm³
Step - by - step equation:
4(5x - 2) = 2(9x + 3)
20x - 8 = 18x + 6
20x = 18x + 6 + 8
20x = 18x + 14
20x - 18x = 14
2x = 14
x = 14 / 2
x = 7

the length of each equal side is 10 ft
the length of the third side is 2 ft
let x be the length of the third side the equal sides are 4x + 2
given perimeter == 22, then
x + 4x + 2 + 4x + 2 = 22
9x + 4 = 22 ( subtract 4 from both sides )
9x = 18 ( divide both sides by 9 )
x = 2 and 4x + 2= 10
