<em>An </em><em>apothem</em><em> is a line from the center of a regular polygon at right angles to any of its sides.</em>
<u>For part A</u>,
We want to find area of pentagon (5 sided figure) given apothem is 1.38 in and side length as 2 inch.
If we look at the picture shown (attached), we can see that a triangle is formed. What is the area of this triangle?
square inches
<u><em>How many such triangles are there in a pentagon? 10. So we multiply 0.69 by 10 to get total area of pentagon.</em></u>
Area of Pentagon = square inches.
<u>For part B</u>,
We want to find area of hexagon (6 sided figure) given apothem is 1.73 in and side length as 2 inch.
If we look at the picture shown (attached), we can see that a triangle is formed. What is the area of this triangle?
square inches
<em><u>How many such triangles are there in a hexagon? 12. So we multiply 0.865 by 12 to get total area of hexagon.</u></em>
Area of Hexagon = square inches.
ANSWER:
Area of Pentagon is 6.9 square inches.
Area of Hexagon is 10.4 square inches.
Answer:
78.5 inch²
Step-by-step explanation:
Given
diameter (d) = 10 inches
radius (r) = 10 / 2 = 5 inches
Area of circle
= πr²
= 3.14 * ( 5)²
= 3.14 * 25
= 78.5 inch²
Answer:there are about the same number of points above the x axis as below it
The points are randomly scattered with no clear pattern, i know that those two are correct but I’m not to sure on the others but i hope this helps!

Answer:
Step-by-step explanation:
<u><em>( 8 ).</em></u> m∠1 = m∠ 4 = m∠ 5 = <em>m∠6 = 52°</em>
<em><u>( 9 ).</u></em> m∠ 2 = m∠ 3 = <em>m∠ 7</em> = m∠ 8 = 180° - 52° <em>= 128°</em>
The original price was $25.
First, convert the 30% to a real mathematical number. For percents, this is always done by dividing the 30% by 100%, or 30% / 100% = 0.300.
Second, find out what 30% of $25 is. This is the amount of the sale discount. This is always found by mulitplying 0.300 by the item's cost $25, like this:
0.300 x $25 = $ 7.50.
So for this sale, you'll save $ 7.50 on this item.
This means, the cost of the item to you is
<span>$25 - $ 7.50 = $17.50.</span>
