Answer:
141.4 sq cm
Step-by-step explanation:
to find the area of the outer circle with a smaller circle inscribed within, you find the area of each and subtract the smaller area from the larger
the radius of the smaller circle is 2
we have to find the radius of the larger circle so we use what we know about its circumference:
C = 2πr
43.96 = 2πr
21.98 = πr
21.98 / π = r
r ≈ 7 cm
now use r = 7 to find area of larger circle:
A = πr²
A = π49
Area of smaller circle: 4π
Area of larger circle without including inner section is 49π - 4π = 45π
45π ≈ 141.4 sq cm
Answer:
I think its 22/25 , 0.8888, and then 8/9
Step-by-step explanation:

Since g(x) varies with x, therefore:
g(x) = k/x where k is a constant.
So, first we need to get k. We are given that g(x) = 0.2 when x = 0.1
Substitute with these values to get k as follows:
g(x) = k/x
0.2 = k/0.1
k = 0.2*0.1 = 0.02
Now, the equation became:
g(x) = 0.02 / x
We need to get the g(x) when x = 1.6
Therefore, we will substitute with x in the equation and calculate the corresponding g as follows:
g(x) = 0.02 / 1.6
g(x) = 0.0125
2v = <-10, 4>
4u = <-24, 4>
-4u = <24, -4>
-4u + 2v = <24, -4> + <-10, 4> = <14, 0>
Answer:
(x + 3) = 9/2
Step-by-step explanation:
Here, we want to write an equation to find the length of the rectangle
Mathematically;
Area of rectangle = length * breadth
15 3/10 = (x + 3) * 3 2/5
(x + 3) = 15 3/10 divided by 3 2/5
(x + 3) = 153/10 * 5/17
(x + 3) = 9/2
