3x=90
x=30
C and D is true and others are false
Area of circle = pi (d/2)^2
area of semi-circle =0.5* pi (d/2)^2
=0.5* pi (6/2)^2
=14.14

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.
