d. Use substitution to predict the cost of the river rafting trip in 2015

a

step-by-step explanation:

step-by-step explanation:

is their an equation anywhere i can take a   look at it and see if i am right.

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
