What is 122?
144
What is the formula to find the radius of a circle?
Diameter/2
What is the formula for finding the area of a rectangular prism?
Length x Width x Height
What is the formula for finding the hypotenuse of a right triangle?
A2 + B2 = C2
5 1/4
What is the approximate square root of 20?
How can you find the diameter of a circle using its area?
You first divide the total area by pi. Then you find the square root of that number to get the radius. And then you multiply the radius by two.
Explain how the surface area of faces of prisms make finding its volume very simple.
If you know the surface area of a prism and you also know the length of the prism, just multiply the surface area that you already by that length and you will get the total volume of the prism.
What is a real-life example of using the Pythagorean theorem?
what is 1/4 +1 3/8?
First, simplify the denominators to 8 makeing the equation 2/8 + 1 3/8 which equals (1 5/8)
Why does 22=4, but 23 not equal 6?
That's because you are always multiplying the number you have by the current number after being multiplied from the first 'powers'. e.g. ( 2x2=4. 2x2=4. 4x2=8)
What is the formula to find the area of a circle?
r2 x pi
How many faces does a right triangular prism have?
5
Which triangles can you use phythagorean theorem with?
Right triangles
What would 8 x 1/4 be?
Another way to look at this fraction is that 8 is divided by 4. (8 x 1/4 = 2)
How do you start to find the square root of a number like 72?
The simpler way:(Find the two perfect squares before and after the selected number.) Extra Brownie Points: Make a line and mark where halfway is, then mark the quarters (1/4 and 3/4). Once these are set, it should be evident where the square root is.
What is circumference?
If a television has an outer shell/frame of metal with measurements 30 inches x 15 inches x 4 inches, how much mass can fit inside it?
30 x 15 = 450
450 x 4 =1800
The total mass that can fit inside the frame/ shell is 1800 inches3.
If you have an equilateral triangle that only gives you the perimeter's measurements, how would you find the vertical height?
First, draw a line in the middle of the triangle to get a right triangle. Then, subtract the base length from the hypotenuse to get the square of your vertical height. Find the square root of the number you just got and that will be your vertical height
What would 7 6/8 be as an improper fraction?
8 x 7= 56
56 + 6 = 62
7 6/8 as improper fraction is 62/8
361
What are the first 5 decimal digits of pi?
3.14159
What is the formula for volume?
What is the hypotenuse of a triangle with a 4 cm long base and a 3 cm tall height?
5 cm. It is also commonly known as a 3,4,5 triangle.
First, we must do the multiplication which is 4/9 x 27/16. After cross-simplified, the equation looks like 1/1 x 3/4 because 4 fits into 16 four times and 9 fits into 27 three times. This equation now equals 3/4. 2/4 + 3/4 = 1 1/4.
