Question

the base of a cone has a radius of 6cm.The height of the cone is 15cm. What is the slant height of the cone?
A.4.85 B. 16.16 C.19.21 D. 5.26

Answer 1

there is a pythagoras formula for this
r^2+h^2=l^2
where r=base radius.,s=slant height, h= height of cone

Answer 2

By Pythagorean Theorem,
l^2 = 15^2 + 6^2

Answer 3

Give a pictorial frame for the question

Answer 4

@KKJ I think I kinda draw out the frame of the question in the drawing. Can you help me check if it's right @selena18 ? Arigato

Answer 5

dont have a drawing for this problem

Answer 6

a^2 + b^2 = c^2
a^2 = 15^2 - 6^2
a ^2 = 189
a = 13.74

Answer 7

is this right?

Answer 8

nopes its 15^2+6^2
not minus.

Answer 9

c=slant height = unknown

Answer 10

15^2+6^2=261

Answer 11

If l is the slant length, then l^2 = r^2 + h^2 where r and h are the radius and height of the cone resp.

Answer 12

yup, now take square root of 261, what do u get ?

Answer 13

its b

Answer 14

yup

Answer 15

thank u so much

Answer 16

l^2 = 6^2 + 15^2
= 36 + 225
= 261
Hence , l = square root of 261
= 16.16 cm

Answer 17

thank u so much for the medal, it was a special one from u, i became 99 :D

Answer 18

The correct answer is B
