Which is the equation of an ellipse with directrices at y = ±2 and foci at (0, 1) and (0, −1)? x squared over 4 plus y squared over 1 equals 1 x squared over 1 plus y squared over 2 equals 1 x squared over 1 minus y squared over 4 equals 1 x squared over 1 minus y squared over 2 equals 1

the answer is c just got it on ed

step-by-step explanation:

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm

you have to put the graph on here with the question
