Acircular clock face is stenciled along its edge. the radius of the clock is 12 centimeters, so the stenciling covers about centimeters. use an estimate of 3.14 for pi.

75.36 centimeters.

Step-by-step explanation:

We have been given that a circular clock face is stenciled along its edge. The radius of the clock is 12 centimeters.

We will use circumference of circle to solve our given problem.

, where,

r = Radius of circle.

Upon substituting our given values in above formula, we will get:

Therefore, the stenciling covers about 75.36 centimeters.

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.
