The diameter of a circular garden is 22 feet, what is the approximate area of the garden?

1) 50 sqr feet
2) 100 sqr feet
3) 254.34
4) 379.94

I hope this helps you

radius=diameter/2=22/2=11

Area =pi.r^2

Area =3,14.11^2

Area =379.94

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
