Answer:
Formula : (n-2) 180
Step-by-step explanation:
12 sides: (12-2) 180
12-2=10
10 * 180= 1800
In the formula the n is the number of sides. Use this formula to solve the first few questions.
The awnser is 5 because 7 divided by 35 is 5
The ratio of perimeters is the same as the ratio of the corresponding sides: 8:9.
_____
Any corresponding length measures of the similar figures will have the same ratio.
Answer:
80
Step-by-step explanation:
You need to calculate the circumference of this wheel to determine how far it travels with each revolution.
First, you need to know the diameter of a circle, which is the length of a straight line drawn through the circle.
You need to calculate the circumference of this wheel to determine how far it travels with each revolution.
First, you need to know the diameter of a circle, which is the length of a straight line drawn through the circle.
The magic number here is pi, which is roughly 3.14159265. The digits to the right of the decimal point continue infinitely.
Dividing a circle’s circumference by pi will give you a circle’s diameter.
Multiplying a circle’s diameter by pi will give you a circle’s circumference.
