Answer #1

Is this analytical geometry…? I’m not 100% sure but work backwards with the circumference. Cirumference = 2pir so 11= 2pi are and pie is a constant so you can get are then frm there just use the formula of an area of a circle… but there must be another way cause I don’t use the 60 digee but maybe that for another question
