Answer:
48 or 47.9
Step-by-step explanation:
The window has a shape of a semi-circle (half of a circle).
We know the diameter d = 12 ft.
The area of a (complete) circle is given by the formula:
A = π × r²
The radius can be found by halving the diameter:
r = d ÷ 2
= 12 ÷ 2
= 6 ft
Therefore the area of the circle will be:
<span>A = π × r²
= 3.14 × 6</span>²
= <span>3.14 × 36
= 113.04 ft²
And the area of the semi-circle:
A = </span><span>113.04 </span>÷ 2
= 56.52 ft²
Hence, the area of the window will be 56.52 ft².
Answer:
80%
Step-by-step explanation:
The percentage change between two numbers can be calculated as ...
percentage change = ((new value)/(old value) -1) × 100%
= (2700/1500 -1) × 100% = (1.80 -1) × 100% = 80%
Traffic volume increased 80%.
14/3 simplified is 4 and 2/3 because 3 goes into 14 a total of 4 times with remainder 2. Therefore, 14/3 simplified is 4 and 2/3 or 4 2/3.
In order to derive the base of a triangle from its area, you need its height as well.
In fact, if we solve the area formula for the base, we have
So, the base length would be
where h is the height relative to the base you're interested in.
