Find the slant height l of the cone given the surface area S.
Oduvanchick [21]

9514 1404 393

Answer:

  15 cm

Step-by-step explanation:

The formula for the surface area of the cone is ...

  A = πr² +πrL =  πr(r +L)

The radius of this cone is half its diameter so is (12 cm)/2 = 6 cm. Then the slant height L can be found from ...

  126π cm² = π(6 cm)(6 cm +L)

  21 cm = 6 cm +L . . . . . . . . . . . . . . divide by 6π cm

  15 cm = L . . . . . . . . . . . . . . . . subtract 6 cm

The slant height is 15 centimeters.

4:7

The least common multiple of 3 and 4 is 12 so...

8:12

  12:21

We add 8 and 12 to get the number of junior members...

8+12=20

Then we put it in a ratio with the amount of adult members...
