Answer:
20π or 62.8 roughly
Step-by-step explanation:
Hello!
<u>The formula for finding the circumference of a circle is 2rπ:</u>
In that case, all we have to do is substitute 10m for our r.
2 × 10 = 20.
So circumference will be 20π.
Using 3.14 for π:
We get that 62.8 is a rough estimate for the circumference.
Really, it's 62.831..... going on forever since π is irrational.
Thus, the answer exactly is .
Hope this helps!
First, let's divide the figure in two parts, called "A" and "B (View the figure attached):
a: The paralelogram
b: The rectangle
To find the area of the parallelogram, we must apply the following formula:
A=bxh
b: is the base of the parallelogram.
h: the height of the parallogram.
We can know the length of the base and the heigh by the figure shown in the problem:
b=4
h=3
Then, we have:
A(a)=bxh
A(a)=4x3
A(a)=12
Now, we must proceed to find the area of the rectangle, by using the formula:
A(b)=bxh
b=9 (the base of the rectangle)
h=3 (the height of the rectangle)
A(b)=9x3
A(b)=27
Then, the area of the figure is:
At=A(a)+A(b)
At=12+27
At=39

b: The rectangle
