Answer:

119 $\frac{4}{7}$

Step-by-step explanation:

10 + 12 + 15 + 24 + 12 + 10 + 35 = 118

$\frac{1}{7} + \frac{2}{7} + \frac{3}{14} + \frac{1}{14} +\frac{2}{7} + \frac{1}{7} + \frac{3}{7} = \frac{11}{7}$

118 + 1 $\frac{4}{7}$

119 + $\frac{4}{7}$

$119\frac{4}{7}$

Explain and correct the error in the example above

Answer:

C = 28.26 cm

Step-by-step explanation:

The figure shows a circle of diameter 9 inches.

The person has taken radius r as 9 inches which is wrong.

The radius must be (9/2) = 4.5 inches, such that,

Circumference = 2πr

= 2×3.14×4.5

= 28.26 cm

Hence, this is the required solution.
