By definition, the volume of a cone is given by:
 V =  \frac{1}{3}  * (\pi) * (r ^ 2) * (h)

 Where,
 r: radius of the circular base
 h: height of the cone
 Substituting values we have:
 V = \frac{1}{3} * (3.14) * (11 ^ 2) * (16)

V = 2026.346667
 Rounding to the nearest hundredth we have:
 V = 2026.35 m ^ 3

 Answer:
 
the volume of this cone is:
 
V = 2026.35 m ^ 3

FrozenT [24]

Answer:

28.26 square inches

Step-by-step explanation:

Formula for area of a circle:

A=\pi r^2

Radius is 3.

A= \pi (3)^2\\A=\pi 9

Use 3.14 for pi:

A = 3.14 * 9 = 28.26\\A=28.26

The area should be 28.26 square inches.

mamaluj [8]

Answer:

Probability of at least two cuckoo eggs is 0.738.

Step-by-step explanation:

probability of cuckoo egg = 0.1

probability of not a cuckoo egg = 1 - 0.1 = 0.9

Probability of at least two cuckoo eggs is

= Probability of two cuckoo eggs x probability of 1 not cuckoo egg +

probability of three cuckoo eggs

= 0.1 x 0.1 x 0.9 + 0.9 x 0.9 x 0.9

= 0.009 + 0.729

= 0.738

Leviafan [203]
The unit rate is going to be calories per serving....calories / serving

Food A :
150 / (3/4) =
150 * 4/3 =
600/3 =
200 calories per serving

Food B :
250 / (2/3) =
250 * 3/2 =
750/2 =
375 calories per serving

Therefore, Food A has fewer calories per serving <==
