6.94-4.99= 1.95
Take the 1.95 divid by the 0.65 per pound and she bought 3 pounds
The formula in getting the ROI or the Return on Investment is ROI = Net Profit/ Total Investment x 100. Below is the solution:
ROI = $ 75,000/$1500 x 100
ROI = $ 5 x 100
ROI = $ 500
You will then divide the $ 500 by 6 to get the ROI per year which is equals to $83.33
The perimeter of the entire figure is 62.8 cm.
Given, that the diameter of the inner semicircles is 9 cm and the width between the outer and inner semicircles is 2 cm.
The radius of the inner semicircle =4.5 cm and the radius of outer semicircle =5.5 cm (∵Diameter=9+2=11 cm)
We need to find the perimeter of the entire figure.
<h3>What is the perimeter?</h3>
A perimeter is a closed path that encompasses, surrounds, or outlines either a two-dimensional shape or a one-dimensional length. The perimeter of a circle or an ellipse is called its circumference.
We know that, the circumference of a semicircle=πr and the circumference of two semicircles=2πr
Thus, the circumference of inner semicircles=2×3.14×4.5=28.26 cm
The circumference of outer semicircles=2×3.14×5.5=34.54 cm
The perimeter of the entire figure=28.26+34.54=62.8 cm
Therefore, the perimeter of the entire figure is 62.8 cm.
