Work out the circumference of this circle. Take a to be 3.142 and write down all the digits given by your calculator.
21 cm

step-by-step explanation: yes

i think that you should ask google for the answer to that problem because if we don't know it google does

1) letter c.

2) 4 square root of 9

hope this

step-by-step explanation:

b: y = 2x + 2

step-by-step explanation:

y = 2x + 1

we want a line that is parallel, so it will have the same slope

the line is in the form y= mx+b, so the slope is 2

we have a slope and the y intercept (0,2)

since x is 0 we know the y point which is the y intercept

we can use y= mx+b to write the equation of the line

m is the slope and b is the y intercept

y = 2x +2
