Answer: 10 units
Step-by-step explanation:
Answer:
113.04 feet²
Step-by-step explanation:
Use the circle area formula, A =
r²
Sine the diameter is 12 feet, the radius is 6 feet
Plug in 6 as r into the formula, and 3.14 as pi, then solve:
A =
r²
A = (3.14)(6²)
A = (3.14)(36)
A = 113.04
So, the area of the circle is approximately 113.04 feet²
20% of 220 is 44 people so if you divide 220 by 2 you have 110 of each then add 44 to one and subtract 44 from the other the answer to a is 154 and the answer to b is 66
<span>Cross multiply:
2 * n = 5 * 12
Simplifying
2 * n = 5 * 12
Multiply 5 * 12
2n = 60
Solving
2n = 60
Solving for variable 'n'.
Move all terms containing n to the left, all other terms to the right.
Divide each side by '2'.
n = 30
Simplifying
n = 30</span>
