Answer:
Step-by-step explanation:
Answer:
B=V/13*h
Step-by-step explanation:
V=13*B*h
V/13*h=B
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>
Answer:
The increase = $0.12
The new price = $1.27
Step-by-step explanation:
1.15 divided by 10% = 0.115 = 0.12
0.12 + 1.15= 1.27
