<u>Answer:</u>
If the circumference of a circle is changed from 9 cm to 3 cm, then the diameter decreases by a factor of 3.
<u>Solution:</u>
Given, the circumference of a circle is changed from 9 cm to 3 cm,
We have to find how will the diameter change from the given equations?
We know that, diameter = 2 
radius and circumference = 2π radius.
Hence, the diameter decreases by a factor of 3.
Answer:
Area of heptagon = 712.26 square units
Step-by-step explanation:
Given the following data;
Side length = 14 units
A heptagon is a polygon with seven sides.
Mathematically, the area of a heptagon is given by the formula;
Area of heptagon = 3.634a²
Where;
a represents the side length.
Area of heptagon = 3.634 * 14²
Area of heptagon = 3.634 * 196
Area of heptagon = 712.26 square units
Do it as simply as possible. 5000 × 2 = 10000. 60 × 10000 = 600000. Because multiplying by a factor of 10 is the easiest possible, always try to get a factor of 10 every time.
Answer:
33.3
Step-by-step explanation:
The formula for area is length*width.
7.4*4.5=33.3
