Question

find the height of a cone whose diameter is 30m and slant height is 25m​

Answer 1

Answer:

r=15m

height of cone=√l²-r²

h=√25²-15²

h=√625-225

h=√400

h=√20²

h= 20m

Answer 2

Answer:

20m

Step-by-step explanation:

height= √ (slanting height)^2 - ( radius) ^2

slanting height= 25m

radius= 30/2= 15m

height= √ (25)^2 - (15)^2

= √400

= 20m
