What is the lateral surface area of a cone with radius 19 cm and slant height 11 cm

Here radius = 19 cm

Slant height =11 cm

The condition for radius and slant height as r<l.

Lateral Surface Area =

=

= 656.59 square cm.

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

the answer is y = 11.54

hope this : )
