Ive thought as much as I could and couldn;t come up with the right answer. The perimeter of a shape is 25.71, calculate the value of radius x, take pi to be 3.142. Perimeter expression = pi x radius + 2 x radius
You will find that the radius is 5. The diameter is 10.
If you are using 3.142 to represent pi, you can check using the formula for perimeter of pi times diameter/2 for a semi circle. Don't forget to add the line segment for the rest of perimeter.
It would look like this: SemiCircle: 3.142(10)/2 = 15.71(distance around semi circle) + 10 (the line segment) = 25.71

In case you have not figured it out.... There are 15 outcomes (1,2,3,4,5) times (red, white, blue). You multiply 5 x 3 for the number of outcomes.
For probability, the number of outcomes will be in the denominator.
For the numerator, it depends on what you are looking for.
For example, the probability of choosing a 1 and getting red.
P(1 and red) would be 1/5 (There's one #1 out of 5 numbers) times 1/3 (Red is one of three colors.)
You find the product of 1/5 x 1/3 = 1/15.

possible side lengths of a rectangular frame are 6 inches, 10 inches, and 12 inches. if all measurements are whole numbers, which dimensions can be used to frame a picture that has an area between 45 and 50 square inches?
Say you receive an email on your school email address from a company that writes maths books for exam preparation. Say they attached a pdf of their Year 8 book and said it was a free give-away and to please pass it on to their students.. how many of the teachers out there would actually pass it on??
Combine like terms for: 5.142r = 25.71
You will find that the radius is 5. The diameter is 10.
