Find cosC sinA, m angle A and m angle C for the triangle

a)(x-2)^2+(y-1)^2=9

step-by-step explanation:

(picture explains)

the circumference of a circle is, 10.676 cm.

step-by-step explanation:

the formula for circumference of a circle is given by:

where

c is the circumference of a circle and

d is the diameter of a circle.

given: diameter(d) = 3.4 cm and use

substitute these values in [1] we get;

cm

therefore, the circumference of a circle is, 10.676 cm
