Question

the volume of right circular cone is 9856 cm3 . if the diameter of the base is 28 cm, find the slant height of the cone.​

Answer 1

Step-by-step explanation:

given,

the volume of right circular cone= 9856 cm³

diameter of the base =. 28 cm

radius =. 14 cm

height =. ?

vol= πr²h/3

9856= 22/7×14×14×h/3

9856= 616h/3

h is equal to 9856×3/616

so height = 48 cm

Answer 2

☁Answer:-

Given

volume = 9856m²

Diameter = 28cm

Radius = 28/2 = 14cm.

i.) slant height of cone

l =  √[h² + r²]

l =  √[(48)² + 14²]

l =  √2304 + 196

l =  √2500

l = 50 cm.

Therefore , slant height= 50cm
