Answer:

42.6m^3

Step-by-step explanation:

Volume of a Cone =\frac{1}{3}\pi r^2 h

Height, h=8.4m

Radius,r =2.2m

Therefore:

Volume of the Right Circular Cone =\frac{1}{3}* \pi *2.2^2 *8.4=42.57m^3

Therefore the volume of the cone is 42.6m^3 to the nearest tenth.

Answer:

The volume of the cone is 42.6 m^3

Step-by-step explanation:

The volume of a cone is given by the area of the base multiplied by the height of the cone and divided by three. The base is a circle, so it's area is computed by the following:

Abase = pi(r^2) = 3.14(2.2^2) = 15.2 m^2

We can then compute the volume of the cone that is:

Vcone = Abase*h/3 = 15.2*8.4/3 = 42.56 m^3

The volume of the cone is 42.6 m^3

Likurg_2 [28]

Answer:

This differs from non-rigid motion, like a dilation, where the size of the object can increase or decrease. When working with rigid motion, you will typically see two objects that show the transformation.

Ipatiy [6.2K]

Answer:

a) r = 0.974

b) Critical value = 0.602

Step-by-step explanation:

Given - Two separate tests are designed to measure a student's ability to solve problems. Several students are randomly selected to take both test and the results are give below

Test A | 64 48 51 59 60 43 41 42 35 50 45

Test B |  91 68 80 92 91 67 65 67 56 78 71

To find - (a) What is the value of the linear coefficient r ?

             (b) Assuming a 0.05 level of significance, what is the critical value ?

Proof -

A)

r = 0.974

B)

Critical Values for the Correlation Coefficient

n       alpha = .05          alpha = .01

4           0.95                       0.99

5           0.878                     0.959

6           0.811                       0.917

7           0.754                      0.875

8           0.707                      0.834

9           0.666                      0.798

10          0.632                      0.765

11           0.602                      0.735

12          0.576                       0.708

13          0.553                       0.684

14           0.532                       0.661

So,

Critical r = 0.602 for n = 11 and alpha = 0.05
