Area of small circle = PI x r^2
r = 1/2 the diameter ( 1/2 * 3 = 1.5)
3.14 x 1.5^2 = 7.065 square cm
there are 2 small circles so total area for them = 7.065 * 2 = 14.13 square cm
the area for the large circle = PI x r^2
the radius of the large circle is 3 cm
3.14 x 3^2 = 28.26 square cm
the area of the shaded area is: 28.26 - 14.13 = 14.13 square cm, which can round down to 14 square cm.
Answer:
5.5
Step-by-step explanation:
So, this is a simple factoring problem. The answer is 5.5(2x-1). So, heres how we get that answer.
So, factoring is basically breaking down the problem into smaller parts. So once we simplify the problem, we can factor it.
- Simplify by combining like terms: 5x+6x= 11x and -2.5-3=-5.5
- Now we have 11-5.5=?
- so, we need to have (2x-1) in our answer because the problem asks for that in the answer.
- We need to find a number that satisfies the equation and answer
- so, 5.5(2x) is 11x, and 5.5(-1) is 5.5.
- 5.5 satisfies the equation, therefore is the answer
