The answer of the following questions is discussed below
<h3>What is area of circle?</h3>
Area of a circle is the region covered or enclosed within its boundary. It is measured in square units.
The radius of each circle
r1= 2.5 inches.
r2= 1 inches
Area of circle large circle,
= πr1²
=3.14*2.5*2.5
=19.625 inch²
Area of small circle,
= πr2²
= 3.14*1*1
=3.14 inch²
Area of large circle minus area of small circle,
= 16.485 inch²

Answer:
78.5
Step-by-step explanation:
The area of a circle is given by
A = pi r^2
Where r is 5
A = pi 5^2
A = 25 pi
We can approximate pi by 3.14
A = 25*3.14
A =78.5
Rectangle does not have equal sides
Step-by-step explanation:
We have to simplify the given expression:
1. 3x+2y-2x+23x+2y−2x+2
Combining the like terms,we get the second step as
2. (3x-2x)+(2y)+(2)(3x−2x)+(2y)+(2)
Now, taking 'x' common from the first two terms, we get third step as:
3. (3-2)x+2y+2(3−2)x+2y+2
Now, simplifying the expressions among the like terms, we get fourth step as:
4. x+2y+2x+2y+2
