Question

find the slant height of the frustum whose radii and height are 17 cm 12 cm and 12 cm respectively​

Answer 1

Answer:

13cm

Step-by-step explanation:

length = root over h^2 + ( r1 - r2 )^2

= root over 12^2 + 5^2

= root over 144 + 25

= root over 169

= 13

Therefore the slant height of the frustrum is 13 cm
