i already did this one step.. confused on what to do next! THANK YOU TO ALL HELPERS I LOVE YOU ALL

Question

"An ice cream company is designing waffle cones to use for serving frozen yogurt. The cross-section of the design has a bottom angle of 29°. The sides of the cones are 13 cm long. Determine the radius of the top of the cone."

Okay, so I already did d^2 = 13^2 + 13^2 -2(13)(13)Cos29, which is d^2 = 42.4.

What would I do next to recieve the radius of the top of the cone?

Answer 1

I don't understand your stumbling block...you already did the hard part!

d is the diameter of the of the top and you have the square...so take the square root of 42.4 and then divide by 2 to get the radius
