Answer:
The difference between the circumference of the tires is 12.56 inches.
Step-by-step explanation:
Given:
Diameter of old bicycle tires = 12 inch
Diameter of new bicycle tires = 16 inch
We need to find the difference in circumference of the tires.
Solution:
First we will find the circumference of Old bicycle tires.
Circumference can be calculated by π times diameter.
Circumference of Old bicycle tire =
Now we will find the circumference of new bicycle tire.
Circumference of New bicycle tire =
Now to find the difference between the circumference of the tires we will subtract Circumference of New bicycle tire from Circumference of Old bicycle tire we get;
framing in equation form we get;
difference between the circumference of the tires =
Hence The difference between the circumference of the tires is 12.56 inches.
Answer:
The length of the other leg of this right angled triangle is 30 inches.
Step-by-step explanation:
We are given the following in the question:
A right angles triangle with the hypotenuse of 34 inches and the length of one of its legs is 16 inches.
Pythagoras theorem:
- The sum of of square of two sides of a triangle is equal to the square of the hypotenuse.
Let x inches be the length of the other leg of this right triangle.
Thus, we can write the equation:
Thus, the length of the other leg of this right angled triangle is 30 inches.
