@ShelbyWyatt i will give you more medals if you help me :)

OpenStudy (shelbywyatt):

ok

OpenStudy (shelbywyatt):

isnt this the same question?

OpenStudy (barrelracing):

wait yea hold on lol

OpenStudy (barrelracing):

here we go

OpenStudy (shelbywyatt):

ok

OpenStudy (shelbywyatt):

so 9 is the radius and 18 is the triangle base

OpenStudy (shelbywyatt):

9*18 then divide by 2 will be the area of the circle

OpenStudy (barrelracing):

ok so 81ft. is it just ft or ft^2 or ft^3?

OpenStudy (shelbywyatt):

ft^2

OpenStudy (shelbywyatt):

then

OpenStudy (shelbywyatt):

we will subtract that from the area of the half circle

OpenStudy (shelbywyatt):

which is 9*9=81 81*3.14

OpenStudy (barrelracing):

173.34?

OpenStudy (shelbywyatt):

254.47

OpenStudy (shelbywyatt):

now divide 254.47 by 2

OpenStudy (barrelracing):

127.235

OpenStudy (shelbywyatt):

yep

OpenStudy (shelbywyatt):

now subtract 127.235 by 81

OpenStudy (shelbywyatt):

it would by ft^2

OpenStudy (barrelracing):

so what is my answer?

OpenStudy (barrelracing):

46.235ft^2?

OpenStudy (shelbywyatt):

wait

OpenStudy (shelbywyatt):

46.235ft^2? yeah

OpenStudy (shelbywyatt):

46.235 ft^2

OpenStudy (barrelracing):

thanks
