Slant height 3

The frustum of a right circular cone has the diameters of base 10 cm of top 6 cm and a height of 5 cm. Find the slant height.

Correct answer:

s =  5.3852 cm

Step-by-step explanation:

d1=10 cm d2=6 m h=5 cm  r1=d1/2=10/2=5 cm r2=d2/2=6/2=3 cm  s2 = (r1r2)2 + h2  s=(r1r2)2+h2=(53)2+52=29=5.3852 cm
