Question

Find the circumference and area of a circle with a diameter of 10 inches. Leave your answers in terms of pi. (4 points)


C = 5π; A = 20π
C = 10π; A = 20π
C = 10π; A = 25π
C = 5π; A = 25π

Answer 1

Circumference of a circle = 2(pi)r
So, r = 5, 5 * 2 = 10, so the final answer for C is 10(pi)
Area of a circle = (pi)r^2
So, r = 5, 5 squared = 25, so the final answer for A is 25(pi)
You can figure out the rest from there :)

Answer 2

so the last choice is right?

Answer 3

Answer 4

No, the third to last choice is right, because it is 'C = 10π; A = 25π'

Answer 5

okay yeah i saw 5 so i thought maybe d.. thank you

Answer 6

No problem :)
