If a = -5 and b = 6, then what does ab equal?

b, i believe, but not sure.

- (2, -7)

- lines r and s and lines t and u must be parallel

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
