Question 152184: Hi
How would I determine the degree of the following polynomial:
(68)1y^1

I solve the following can you tell me if it right I have been out of school for 15years and I not sure of these problems:
vi. A function gives the value of C as 2 × (22/7) × r. Find C when r = 21 cm and r = 84 cm.
First I plug in 21 for r:
C = 2 × (22/7) × 21
C = 132 cm
And plug in 84:
C = 2 × (22/7) × 84
C = 528 cm
Thank you for your Help
