Find the volume of the cone shown as a decimal rounded to the tenth. 22m 12m

Mathematics
1 answer:
Luda [366]2 years ago
3 0

Answer:

b

Step-by-step explanation:

the volume (V) of a cone is calculated as

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

here diameter = 12 , so r = 12 ÷ 2 = 6 and h = 22 , then

V = \frac{1}{3}π × 6² × 22

   = \frac{1}{3}π × 36 × 22

    = \frac{1}{3}π × 792 ( cancel 3 and 792 by 3 )

    = π × 264

    ≈ 829.4 m³ ( to the nearest tenth )
