Plz teach me

Answer 1

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

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

Answer 2

@Qwertty123

Answer 3

C= 10pi, A= 25pi

Answer 4

can you show me how to do it tho

Answer 5

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 try figure out the rest from there... :3

Answer 6

Error1603, you need to stop giving direct answers..

And you have an equation for the Circumference which is:\[C =\pi(d) \]
or\[C =2\pi(r)\]

Answer 7

ok thanks

Answer 8

The easiest one to use here would most likely be C = pi (d)

Answer 9

Good job @ShootingStar28
