Answer:
48 cm²
Step-by-step explanation:
Area
= (6 x 2) + (10 - 6) x 9
= 12 + 36
= 48 cm²
The empirical rule for normal distributions states that approximately 68% of the data points lie within the range plus and minus one standard deviation of the mean.
The answer is 68%.
I saw the diagram.
1) radii: CD, CG, CF, CE, CH
2) diameter: DG, EF
3) radius: 14cm/2 = 7cm
4) diameter: 14cm because DG is the diameter, its measure is the measure of the diameter.
5) Circumference = 2 π r = 2 * 3.14 * 7cm = 43.96cm
6) Area = π r² = 3.14 * (7cm)² = 3.14 * 49cm² = 153.86 cm²
