62 square cm is the answeree

Well, assuming the square painting has a side length of 62 cm on ONE side only (meaning the other 3 sides will be the  same) then we can use the normal area equation for squares. Area=S^2, where s is the side length of 1 side.
So, put in your info: Area=62^2. 
62^2=62*62 basically. That equals 3844

Assuming that 62 cm is the length of only 1 side of the square, your answer is 3844 cm^2.<span />

Taya2010 [7]

Answer:

I'm not sure what you are looking for but I'm assuming you are finding r.

r is equal to 4.

Step-by-step explanation:

6 = r + 2

In order to find r, you have to subtract 2 from 6.

So, r = 6 - 2 = 4

Complete Question

The complete question is shown on the first uploaded image

Answer:

The value is  y  =  5sin3x

Step-by-step explanation:

From the question we are told that  

   y =  c_1\ cos3x + c_2 \  sin 3x

given that y(0) =  0

We have that  

     c_1\ cos3(0) + c_2 \  sin 3(0)  =  0

=>   c_1 =  0

This means that

           y  =  c_2 \  sin 3x

We also given that

          y[\frac{\pi}{6} ] =  5

So  

         c_2  sin (3 *  \frac{\pi}{6} )  =  5

=>    c_2  =  5

Hence  

     y  =  5sin3x
