Answer:
Step-by-step explanation:
1 2 3 4 5 6
Twice of 2^30= 2*2^30= 2^31
10 pieces because five plus five is ten
We know that
[volume of a cone]=pi*r²*h/3
h=30 cm
volume=1440*pi cm³
r²=3*volume/[pi*h]------> r²=3*1440*pi/[30*pi]----> r²=144-------> r=√144
r=12 cm
so
the diameter=2*r------> 2*12-----> 24 cm
the answer is
<span>the diameter of the cone's base is 24 cm</span>
