What is the approximate circumference of a semicircle with a radius of 30 centimeters
Dmitry [639]

Approximate circumference of a semicircle with a radius of 30 centimeters is 94.2 centimeter

<em><u>Solution:</u></em>

Given semicircle with a radius of 30 centimeters

<em><u>To find: approximate circumference of a semicircle</u></em>

To find circumference of semicircle we can divide the circumference of circle by 2

circumference of semicircle = circumference of circle \div 2

\text{ circumference of semicircle} = \frac{2 \pi r}{2} = \pi r

Substituting the given radius = 30 cm,

\text{ circumference of semicircle} = 3.14 \times 30 = 94.2

Thus approximate circumference of a semicircle with a radius of 30 centimeters is 94.2 centimeter

Chloe purchased a sweater that cost $24, and a shirt that cost 5/8 times as much as the sweater.What amount of change did Chloe
KatRina [158]

Answer:

Chloe received $11 as change if she gave the clerk $50

So, Change received by her = 50-39=11

So, Chloe received $11 as change if she gave the clerk $50
