D would be the correct answer. Post brainliest if this helped plz :)
The circumference is about 3.14 (
) times bigger than twice the radius. Mathematically, this can be writted as
, where C equals the circumference and r equals the radius, or
where C equals the circumference and d equals the radius.
The angle = 360° * 0.67 = 241.2
And by rounding to the nearest degree = 241°
The correct choice is number 4
a). (20 x 80) + (20 x 6) + (7 x 80) + (7 x 6)
