Mathematics
1 answer:
Doss [256]3 years ago
8 0

Answer:

Volume of the cone =650.06 cubic feet

Step-by-step explanation:

Height of the cone= 14.7 feet

Circumference= 13 feet

Radius = 13/2 = 6.5 feet

Volume of the Cone:

         =\pi r^2\frac{h}{3}

As, \pi =\frac{22}{7}=3.14

Putting the values in the formula:

Volume of the cone is :

          =3.14*(6.5*6.5)*\frac{14.7}{3} \\\\=3.14*(6.5*6.5)*4.9\\\\=3.14*42.25*4.9\\\\=3.14*207.03\\\\=650.06feet^3

Volume of the cone is 650.06 cubic feet

nika2105 [10]

Answer: -44

Step-by-step explanation: PEMDAS(Parenthesis; Exponent; Multiply; Divide; Add; Subtract)

First you multiply the seven with the other seven to get 49. The problem will look like this: (-3) + 8 - 49. Now just add the -3 and 8. You'd get 5.

Now the problem looks like this: 5 - 49. And you then get -44.

MAXImum [283]

Answer:

There are a total of 4 + r + 6 marbles in the bag

The probability of a blue is  \frac{4}{10+r}  

The probability of a red is  \frac{r}{10+r}  

The probability of choosing a blue, replacing it and then a red is

\frac{4}{10+r} × \frac{r}{10+r}  =  [tex]\frac{4r}{100+20r+ r^{2} /[tex]
