Answer:
<h2><u><em>
8 ft</em></u></h2>
Question:
The circumference of a circle is 16Pi ft. so what is the radius?
Step-by-step explanation:
To calculate the circumference of a circle, multiply the diameter of the circle with π (pi). (The circumference can also be calculated by multiplying 2×radius with pi (π=3.14)).
16 : 2 =<u><em> </em></u><u><em>8</em></u>
Answer:
For line j to be parallel to line k, then x has to be equal to 0
Step-by-step explanation:
if line j is parallel to line k, then the two angles are equal.
They are equal because they would be alternate angles and alternate angles are equal in value
Thus,
3x + 10 = 5x + 10
5x-3x = 10-10
2x = 0
x = 0
Answer:
5981.25 m²
Step-by-step explanation:
1. Divide the court into two sections. One section being the semicircle, the other being the rectangle.
2. Multiply 100 by 50 to get the area of the rectangle, which is 5000.
3. Divide 50 by 2 to get the radius of the semicircle, which is 25.
4. Find the formula used for area of a semicircle A = 
r²
5. Insert 25 into where the "r" is in the equation: A = (25²), resulting in about 981.25. (I replaced with 3.14)
6. Add the area of the rectangle with the area of the semicircle, 5000 + 981.25 = 5981.25.
7. The final answer is 5981.25 m².
4/20 has the numbers 4 and 20 which can be simplified
2/10 is the same as 4/20 when you multiply both numbers by 2
and 1/5 is the simplest answer and is the same as 4/20 when both numbers are multiplied by 4
Hope this helps! :D
