#

area of a circle is pir^2

#

you can find r

#

by finding distance from origin to centre of circle since the circle passes through the origin

#

to find the distance you can use Pythagoras

omd

#

sorry

shut bridge
#

it’s okay haha that’s the tricky part 😭

clever spire
#

so you have the equation of the circle right

#

in terms of a

#

you know two points on the circle

#

so you can get two equations in terms of a

shut bridge
clever spire
#

im not sure 😂

shut bridge
clever spire
#

im actually so confused

#

did you get the equation of the circle as (x-a)^2 + (y+a)^2 = rt2a

shut bridge
#

what’s rt2a?

shut bridge
clever spire
#

(2)^1/2 * a

shut bridge
#

i got (x-a)^2 + (y+a)^2 = r^2 as the equation of the circle

clever spire
#

ye

#

ohhhh

shut bridge
#

yeaaah it works

clever spire
#

i had the equation as

#

the same thing but r

shut bridge
#

ohhh

clever spire
#

instead of r^2

shut bridge
#

you sqrted

#

fairs

#

thanks :)

clever spire
#

wait so did you do part b?

shut bridge
#

yeah

clever spire
#

whats the answer

shut bridge
#

338pi according to me

#

idk if i’m right

clever spire
#

what did you get the radius as?

shut bridge
#

13 sqrt 2

clever spire
#

mm i got 169/18 pi as area

shut bridge
#

what’s your radius

#

and what’s your centre

clever spire
#

i got a =13/6

shut bridge
#

i got 13

clever spire
#

12a=26

shut bridge
#

how

clever spire
#

-2a-10a

shut bridge
#

OHMYGOD

#

i’m so dumb thank you

clever spire
#

no problem
