What is the length of the radius of the larger cone(the larger cone has a slant height of 15) when the smaller cone has a radius of 8 and a slant height of 12ft , .

The radius of the larger cone is equal to 10 ft.

Step-by-step explanation:

For the smaller cone, we have:

radius = r = 8 ft

slant height = l = 12 ft

slant angle = Ф = sine inverse(l/r)

= sine inverse(8/12)

Ф = 42°

Now

For larger cone, with same slant angle,

Slant height = 15 ft

Radius = r =?

r = l sin(Ф)

r = 15*sin(42°)

r = 15*0.669

r = 10 ft

Hence, the radius of a cone with slant height 15 ft and slant angle 42° would be equal to 10 feet.

step-by-step explanation:

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,
