If the area of a circle is 31.36 pi, then what is its radius?

mixas84 [53]

Answer:

5.6 units

Step-by-step explanation:

$\boxed{area \: of \: circle = \pi {r}^{2} }$

Given that the area of the circle is 31.36π,

31.36π= πr²

Divide both sides by π:

31.36= r²

r²= 31.36

Square root both sides:

$r = \sqrt{31.36}$

r= 5.6 units

Sum10and product of 9

AVprozaik [17]

Answer:

$x+ y = 10 ---(1)\\ x\cdot y = 9 ---(2)\\\\from(2) \ y = \frac{9}{x}\\\\substitute \ y \ in (1) \\x + \frac{9}{x} = 10\\\\x^2 + 9 - 10x = 0\\x^2 -10x + 9 = 0\\x^2 -9x -x +9 = 0\\x(x-9)-1(x-9)=0\\(x-1)(x-9)=0\\x = 1 \ or \ 9\\$

substitute x in y = 9/x

=> y = 9 or 1

So the number are 1 and 9 or 9 and 1
