Answer:

Circumference of the circle = 44 m
Circumference Formula = 2πr
Let's take the radius as 'r' m.
Radius (r) =

Area of the circle = πr²

=> Area of the circle = <u>153.86 m² = 154 m² (approx.)</u>
<h2>
Explanation:</h2>
Here we have the following expression:

So we can rewrite this as follows:

So this is an arithmetic series whose general form is given by:

Where:

So, for some n-values we have:

From this information, the diagram that best represents the given expression is shown below.
It is said that the graph plotted is the money spent to the number of items of clothing bought.
It will look like this:
The domain by definition is the set of inputs.
The constraint on the domain here is the monthly spending cannot be greater than $50.
So the domain will be [0,50] in dollars on the x-axis.
Answer:
a = 5/6 , b = -3/10
Step-by-step explanation:
3a-5b:3a+5b=1:4
3a-5b / 3a +5b = 1/4
Cross multiply
3a -5b =4 ..........(1) solve simultaneously
3a + 5b = 1 ..........(2) using elimination method
-----------------------
Add equation 1 and 2
6a = 5
Divide both sides by 6
6a/6 = 5/6
a =5/6
Put value of a into equation 2
3a +5b = 1
3(5/6) + 5b = 1
5/2 + 5b = 1
5b = 1 - 5/2
5b = - 1½
5b = - 3/2
Divide both sides by 5
5b/ 5 = -3/2 ÷ 5
b = -3/2 × ¹/5
b = - 3/10
Therefore a = 5/6 , b = -3/10
