Answer:
38.465 ft²
Step-by-step explanation:
the area of a circle can be calculated using the following formula:
the radius is half of the diameter:
Answer:
x = 8
m∠BOC = 37°
m∠AOB = 53°
Step-by-step explanation:
If OA is perpendicular to OC, this means that <AOC = 90°
Given
m∠BOC=6x−6
m ∠AOB = 5 x + 8
The expression is true
m∠BOC+m∠AOB= m∠AOC
6x-6+5x+8 = 90
Find x:
11x + 2 = 90
11x = 90-2
11x = 88
x = 88/11
x =8
Get m∠BOC:
m∠BOC= 6x-6
m∠BOC= 6(8)-11
m∠BOC = 48-11
m∠BOC= 37°
Get m∠AOB;
m∠AOB = 90-m∠BOC
m∠AOB =90-37
m∠AOB = 53°
Answer: A -22 can be a rational number as well as a integer
Step-by-step explanation:
Whole Number: A whole number is not a fraction or a decimal so a example would be: 43 or 85 or 1 or 3. Zero is not a whole number. Negative are not whole numbers
Rational number: A rational number is a number that can be expressed as a fraction or a decimal. Like 33 can be 33/1. Most numbers are rational. Zero is a rational number.
Integers: A integer is not a fraction or a decimal. its a positive or negative number. Example: 1 or -5 or 85 or -445. there is still some arguments about if zero is a integer.
Irrational numbers: A irrational number cannot be expressed as a ratio. So for example pi: 3.141592653589......(it keeps on going, we haven't even gotten to the end because its infinite).
Natural numbers: Natural numbers are positive numbers. Example: 1,6,3,4,62,3 etc. Sometimes zero is a natural number.

Step-by-step explanation:
For 3 side lengths of a triangle to form a right triangle, the sum of the squares of the 2 smaller side lengths must be equal to the square of the largest side. (a² + b² = c²)
Since 1² + 2² =/= 5², (5 =/= 25)
it will not form a right triangle.
Another Explanation:
Since 5 > 1 + 2, the sum of the 2 smaller side lengths is less than the largest side. Hence it will not form a triangle => not form a right triangle.
It would be negative six.
