The volume of a right cone is 21 pi units. If its circumference measures 6 pi units, find its height.
1 answer:
<h3>

</h3>
<u>Given,</u>
Volume of cone = 21π cm³
& It's Circumference = 6π
Find Radius,
★ Circumference = πr²
=> 6π = πr
=> 6π/π = r
=> r = 6 cm
Now,
★Volume of cone = 1/3πr²h
<h3>

</h3>
<h3>★Hence, The value of height is 1.75 cm</h3>
Hope it helps youu....!!!
