Vol of sphere =4/3πr³ 
let the radius of cone be x. 
vol of cone =1/3πx²h 
when h=r, =1/3πrx²
since they have the same volume, 
4/3πr³=1/3πrx²
4πr³=πrx²
x²=4r²
x=2r (radius)

 Hi there! :)
Answer:

m∠BGC = 16x - 4
m∠CGD = 2x + 13
m∠BGC + m∠CGD sums up to 90°, therefore:
(16x - 4) + (2x + 13) = 90
Combine like terms and simplify:
16x + 2x - 4 + 13 = 90
18x - 4 + 13 = 90
18x + 9 = 90
18x = 81
18x/18 = 81/8
x = 4.5
