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.

do you mean add both of the equations together

because if you do the answer is 10x-5

step-by-step explanation:

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.
