Answer
: 4.5
Step-by-step explanation:
a^2+b^2=c^2
4^2+2^2=20
Square root of 20 = 4.5
Answer:
1 / 36
Step-by-step explanation:
So there's one number on a cube greater than 5. That is 6.
There is 1 / 6 chance of getting 6 the first time, and another 1 / 6 change for getting 6 the second time.
1 / 6 * 1 / 6 = 1 / 36
Answer:
Step-by-step explanation:
Always proceed by first extracting all common factors to all terms:
Notice that the factors: 5, x, and y are present in all terms, so we can extract them from the trinomial:
Now, the trinomial left (-x+2-3y) cannot be factored out, so then factoring is complete.
Answer:
πr²/4
Step-by-step explanation:
Area of a circle if πr²
so Area of a quarter of a circle (or 1/4 of a circle) = πr²÷4
Answer:
Radius is 2 centimeters
Step-by-step explanation:
<u>4π is the area of a circle</u>
<u>Area of a circle = πr^2</u>
4π / π = πr^2 / π
sqrt(4) = sqrt(r^2)
2 = r
Answer: Radius is 2 centimeters
