jim_thompson5910 · Answer

the angle of the sector is 360 - 300 = 60 degrees

jim_thompson5910 · Answer

now you use this formula

A = (angle/360)*pi*r^2

and plug in the given info to get

A = (60/360)*pi*13^2

A = ???

anonymous · Answer

Remember that the area of a (whole) circle is:
$$A=\pi r^2$$ We know the radius from the picture. So we simply need to figure out what fraction of the circle this sector is.

a = 60 / 360 = 0.17 x 3.14 x 169 = 90.21 @jim_thompson5910

jim_thompson5910 · Answer

I'm getting (60/360)*3.14*13^2 = 88.443333333333, so you're close, but also a bit off

jim_thompson5910 · Answer

it's best not to go to decimal form if you can avoid it

anonymous · Answer

wait how did u get that
:/ ???

jim_thompson5910 · Answer

typing (60/360)*3.14*13^2 into the calculator exactly as you see it

jim_thompson5910 · Answer

google acts like a calculator when you type that exact thing in https://www.google.com/search?hl=&q=%2860%2F360%29*3.14*13^2&sourceid=navclient-ff&rlz=1B3GGLL_enUS420US420&ie=UTF-8
