hope i can help, of so may i have brainliest, i want my level up
Volume of the sphere = (4/3) pi (5a)^3
Volume cone = (1/3) pi (3a)^2 * h (h = height).
(4/3) pi 125a^3 = (1/3) pi 9a^2 h
(4/3) * 125a^3 = (1/3) 9a^2 h
h = (4/3) * 125 a^3
-------------------- = 4 * 13.889 a
(1/3) 9 a^2
h = 55.56 cu units to nearest 1/100
By my count, the number is 9 followed by 18 zeros. If that is so, it is 9 Quintilian in modern counting. The old British system would count it as 9 Trillion. The debt, always counted in American dollars, is 21 trillion which is 21 followed by 12 zeros. So the American and Old British systems are quite different.
