<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....!!!

The vertices for the dilated image can be found by multiplying the coordinates of the original image by the scale factor. In this problem, the scale factor is 1/3.
(0,0) ⇒ 0 x 1/3 = 0 ; 0 x 1/3 = 0 ⇒ (0,0)
(27,0) ⇒ 27 x 1/3 = 9 ; 0 x 1/3 = 0 ⇒ (9,0)
(36,30) ⇒36 x 1/3 = 12 ; 30 x 1/3 = 10 ⇒ (12,10)
(9,30) ⇒ 9 x 1/3 = 3 ; 30 x 1/3 = 10 ⇒ (3,10)
Answer is choice D. (3,10)
