Answer:

A) 4.5 cm

Step-by-step explanation:

Given: Circumference of the circle = 28.3 cm

Here we are asked to find the radius "r".

2.π.r = 28.3

The value of π = 3.14

2*3.14.r = 28.3

6.28r = 28.3

Dividing both sides by 6.28, we get

r = 28.3/6.28

r = 4.5 cm.

The radius of the circle r = 4.5 cm

Answer: A) 4.5 cm

Thank you.

Find 8 and one third percent of 144
madam [21]
\bf 8\frac{1}{3}\implies \cfrac{8\cdot 3+1}{3}\implies \cfrac{25}{3}
\\\\\\
now\qquad \cfrac{\frac{25}{3}}{100}\implies \cfrac{\frac{25}{3}}{\frac{100}{1}}\implies \cfrac{25}{3}\cdot \cfrac{1}{100}\implies \cfrac{1}{3\cdot 4}\implies \cfrac{1}{12}
\\\\\\
8\frac{1}{3}\%\ of\ 144\implies  \left( \cfrac{\frac{25}{3}}{100} \right)\cdot 144\implies \cfrac{1}{12}\cdot 144\implies \cfrac{144}{12}\implies 12
