If the circumference of a circle is about 15.4 cm, estimate to the nearest whole number the diameter of the circle
nasty-shy [4]

The nearest whole number the diameter of the circle is 5.0 cm.

<u>Given the following data:</u>

  • Circumference of a circle = 15.4 cm

To estimate to the nearest whole number the diameter of the circle:

In this exercise, you're required to solve for the diameter of a circle and round up its value to the nearest whole number.

<h3>How to calculate the circumference of a circle.</h3>

Mathematically, the circumference of a circle is given by the formula:

Circumference = \pi D

<u>Where:</u>

  • D is the diameter of a circle.

Making D the subject of formula, we have:

D =\frac{circumference}{\pi}

Substituting the given parameters into the formula, we have;

D =\frac{15.4}{3.142}

D = 4.90 cm

To the nearest whole number:

D = 4.90 ≈ 5.0 cm

The area of the shaded region
antiseptic1488 [7]

Answer:

125.66cm²

Step-by-step explanation:

so you need to find the area of the big circle and subtract it from the area of the small circle

area of a circle= π r²

small circle: substitute in what you know

a= π x 3²

a= 28.2743

big circle: substitute in what you know

a= π x 7²

a= 153.9380

now do 153.9380-28.2743=125.6637

now round this number to the nearest hundredth:

125.66cm²
