We know that
the volume of a cone=(1/3)*pi*r²*h
where
r is the radius
h is the height
in this problem
diameter=2 cm
so
r=diameter/2-----> r=2/2-----> r=1 cm
h=2 cm
volume of a cone=(1/3)*pi*1²*2------> 2.09 cm³------> 2 cm³
the answer is
2 cm³
Answer:
Circumference is times 4
Step-by-step explanation:
Area is proportional to r²
Area is times 16
Radius is times 4
Since circumference is 2pi×r, it's proportional to r
So circumference is also times 4
Circumference: 2 × pi × (4×11.6)
92.8pi in
