Find the Volume (look at the picture)
xeze [42]

Answer:

V ≈ 263.9 units³

Step-by-step explanation:

The volume (V) of a cone is calculated as

V = \frac{1}{3} πr²h ( r is the radius and h the height )

Here r = 6 and h = 7 , then

V = \frac{1}{3} π × 6² × 7

   = \frac{1}{3}π × 36 × 7

   = \frac{1}{3}π × 252

   = 84 π

   ≈ 263.9 units³ ( to 1 dec. place )
