Answer
Explanation:
Step1: Find the diameter
From the graph, the distance between the two black points (which is the diameter) is (d = 2) units.
Step2: Calculate the circumference
The formula for the circumference of a circle is (C=\pi d). Substituting (d = 2) and (\pi=3.14), we get (C = 3.14\times2=6.28) units.
Step3: Calculate the radius
The radius (r=\frac{d}{2}). Since (d = 2), then (r = 1) unit.
Step4: Calculate the area
The formula for the area of a circle is (A=\pi r^{2}). Substituting (r = 1) and (\pi=3.14), we get (A=3.14\times1^{2}=3.14) square units.
Answer:
(C = 6.28) units, (A=3.14) units²
