Answer:
(Construct circle with a compass)
Area: 12.56
Circumference: 12.56
Explanation:
formula for the area of the circle:
A = 3.14 · r²
A = 3.14 · 4
A = 12.56
formula for the circumference of the circle:
C = 3.14 · d
to find the diameter of the circle, multiply the radius by 2
2 · 2 = 4
C = 3.14 · 4
C = 12.56
