Question

Evaluate C= 2 兀 r, for r= 8.
O C = 16
O C= 10 兀
O C= 28 兀
O C= 16 兀

Answer 1

C = 16 π

Step-by-step explanation:

If C = 2 π r, and r = 8:

C = 2 π (8)

Simplify (multiply 2x8):

C = 16 π

Answer 2

The correct answer is C = 16 兀

Step-by-step explanation:

In this problem, C represents the cost and r represents the rate. The formula for calculating the cost is C = 2 * r, where C is the cost in 兀 and r is the rate in 兀/unit.

When r is 8 兀/unit, the cost is C = 2 * 8 = 16 兀.
