Question

if the radius of the circular base of a frustum of acone are 33 and 27 and its slant heigjt is 10 find the height of the frustum
​

Answer 1

Answer:

8

Explanation:

R = 33, r = 27 & slant height l = 10

height = √[(10^2 -(33-27)^2 ]

height = √(100 - 36) = √64 = 8

Answer 2

Answer:

height of frustum = 8cm

Explanation:

radius of upper surface = R = 33cm

radius of lower surface = r = 27cm

slant height of frutum = l = 10cm

h^2 = {l^{2} - (R-r)^{2} ]

h^2 = {10^2 - (33-27)^2}

h^2 = {100 - 36}

h^2 = {64}

h = 8 cm
