Answer:
Step-by-step explanation:
Let x is the length of the square side.
We know: the two figures have the same area
<=> 
= π
(r being radius)
<=> x = 
r
perimeter square = 4x = 4*r*
perimeter circle = 2*r*π
<=> 390 = 4*r* + 2*r*π
<=> r = 29.16
=> perimeter square = 4*29.16*π
=> perimeter circle = 58.32π
Answer:3 is your answer
Step-by-step explanation:
3 x 6 = 18
Answer:
8
Step-by-step explanation:
Answer:
First it says that you have to multiply the number x times 2, this will give you 2x as a result. Next you have to build your equation which is 2x=10, when you have an equation like this, you divide the result with the number before x (x=10÷2) your result will be x=5. Now you have to square the result (which is x) to get y, when squaring a number you have to multiply it by itself (depending of how many times it's asking to do so when there's a small number at the upper right corner of your number, that's how many times you multiply it) so if you have to square 5, it should be 5×5 which gives you the result of y being 25.
