What is the area of the circle? use 3.14 for π

a) 12.56 mm2
b) 25.12 mm2
c) 50.24 mm2
d) 502.4 mm2

We know the radius of the circle is 4mm. And pi is 3.14 the formula is A=pi(r)2 so 3.14(4)^2= 50.24 and that's your final answer. (C)
 Hope it helps :)

The equation we will use for this is πr^2,

knowing this we will plug everything.

now we have 3.14×4^2(16).

3.14×16=50.24

Therefore the answer you are looking for is C. 50.24

-I hope this is the answer you are looking for, feel free to post your questions here on in the future.

Iwould say that is c
