Area of the small circle = 
r
= 3.14 x 7= 153.86
Area of the big circle = R=3.14 x 14= 615.44
The shaded area = area of the big circle - area of 2 small circle = 615.44-2x153.84≅308
The answer is 308
Well lets look at this
First figure out: How many milliliters are in a liter: 1000
Ok now you need half a liter so how would you figure out how many milliliters that is?
Divide by 2: 1000 ÷ 2 = 500
So 500 milliliters are needed for half a liter
1. A
Two triangles are said to be in perspective (or as some would call it, homologous) from a point if their corresponding vertices form three lines that intersect in that single point (called a colinear point). Desargues' theorem asserts that if two triangles are in perspective from a point, then they are also perspective from a line (called the perspectrix<span>); for this reason perspective triangles are also calles coplanar triangles.

</span>The series of numbers shown in the question is known as the Fibonacci Sequence. <span>The next number in the sequence is found by finding the sum of the two numbers that precede it.
</span>
1 = 0+1
<span>2 = 1 + 1
3 = 1 + 2
5 = 3 + 2
8 = 5 + 3
Next number is 13 (8 + 5)</span>
