Option A
The radius of circle is 19.90 cm
<h3><u>Solution:</u></h3>The formula for circumference of circle is given as:
Where,
"C" is the circumference of circle
"r" is the radius of circle
is a constant equal to 3.14
Given that, circumference = 125 cm
To find: Radius of circle
<em><u>Substitute the given value of "C" = 125 in formula</u></em>
Thus radius of circle is 19.90 cm
The volume of the solid is which is a cone is 100.48 .
Given a cone of radius 4 km and height being 6 km.
We are told to find the volume of the cone.
Volume is basically the amount of a substance that a container can hold in its capacity.Its value cannot be equal to zero or negative. It is basically amount of filling in a container.
Volume of cone is 1/3 .
Volume =1/3
=1/3 π*16*6
=32π
=32*3.14
=100.48
Hence if the radius of the cone is 4 km and height be 6 km then the volume of the cone is 100.48.
