Answer: b) Large blue t-shirt & Medium RC jeans

<u>Step-by-step explanation:</u>

The subscript numbers attached to the matrix letter represents the:

ROW, COLUMN

$A=\left[\begin{array}{ccc}a_{1,1}&a_{1, 2}&a_{1, 3}\\a_{2,1}&a_{2, 2}&a_{2, 3}\\a_{3,1}&a_{3, 2}&a_{3, 3}\end{array}\right] \qquad B=\left[\begin{array}{ccc}a_{1,1}&b_{1, 2}&b_{1, 3}\\b_{2,1}&b_{2, 2}&b_{2, 3}\\b_{3,1}&b_{3, 2}&b_{3, 3}\end{array}\right]\\$

A₁,₃ = 1st row, 3rd column

1st row is Blue, 3rd column is Large

B₃,₂ = 3rd row, 2nd column

3rd row is RC jeans, 2nd column is Medium

A₁,₃ + B₃,₂ = Large blue t-shirt & Medium RC jeans

The height and radius of a cone are each multiplied by 3. What effect does this have

Black_prince [1.1K]

The volume of the original cone is multiplied by 27

<h3><u>Solution:</u></h3>

We have been given that the height and radius of a cone are each multiplied by 3.

We need to find what effect it has on the volume of the cone.

<em><u>The volume of the original cone is given as follows:</u></em>

$\text {Volume of cone}=\frac{1}{3} \pi r^{2} h$

Now, the radius and height are multiplied by 3.

Therefore, the new radius is ‘3r’ and the new height is ‘3h’.

Hence the new volume is

$\text {Volume of new cone}=\frac{1}{3} \pi(3 r)^{2}(3 h)=9 \pi r^{2} h$

original volume of cone x 27 = volume of new cone

Therefore, the original volume of cone is multiplied by 27
