Question

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

Answer 1

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 :)

Answer 2

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
