$\sqrt{\pi } = 1.772$
$\pi = 3.142$
$2 \times \pi = 6.283$
${\pi}^{2} = 9.869$

9.A
3/2=1.5

8. F
2times pi =6.283
square root of 50= 7.071
pi squared/2= 3.289

10.H

What is a percentage increase of 19.50 to 22.50

Inga [223]

To find the percentaje we need to divided the tataol by the amount we end up having.

22.50/19.50=1.15
then we multiply by 100
115%
Then to find the percentaje increase we subtract
115%-100= 15%
So it has an increament of 15%
