A circular placemat has 44 inches of braid around the edge. What is the area of the placemat to the nearest square inch? Use 3.14 for π.
Enter the correct answer in the box.
[ ]
==========================================================
Explanation:
We'll need to use the circumference formula
C = 2*pi*r
to find the value of the radius r when C = 44
So we get
C = 2*pi*r
44 = 2*3.14*r
44 = 6.28*r
6.28r = 44
r = 44/6.28
r = 7.0063694267516
which is approximate
Then we use this value of r to find the area we need
A = pi*r^2
A = 3.14*(7.0063694267516)^2
A = 154.140127388536
A = 154
The area of the circular placemat is approximately 154 square inches.
Answer:
a ~ 154
a = [tex]\frac{484}{(pi)}[/tex]
Step-by-step explanation:
1. Approach
In this problem, one is given the circumference, the distance around the circle, one must find the area. In order to find the area, one must know the radius of the circle. To find the radius, one has to backsolve from the given circumference, then substitute the derived value into the formula for the area and solve.
2. Find the radius
The formula to find the circumference of a circle is;
[tex]2r(pi)=c[/tex]
Where (r) is the radius, (pi) is (3.1415), and (c) is the circumference.
Substitute in the given values and solve;
[tex]2r(pi) = c\\2r(pi) = 44\\r=\frac{44}{2(pi)}\\r=\frac{22}{(pi)}[/tex]
3. Find the area
Now, one has the value of the radius, substitute it into the formula for the area of a circle and solve;
The formula for finding the area of a circle;
[tex](pi)r^{2}=a[/tex]
Where (pi) is (3.1415), (r) is the radius, and (a) is the area,
Substitute in the value and solve.
[tex](pi)r^{2} = a\\(pi)(\frac{22}{(pi)})^{2}=a\\\frac{(22)^{2}}{(pi)}=a\\\frac{484}{(pi)}=a[/tex]
a ~ 154

It takes Jonas 7 1/4 minutes to run the mile. It takes Mario 8 5/12 to run the mile. How much faster is Jonas than Mario?
5/6 minute
1 1/3 minutes
1 1/6 minutes
1 1/2 minutes
sean runs 2/3 of a mile in 10 minutes. at this rate how many miles can sean run in 30 minutes. Explain.
Answer:
2 or 6/3
Step-by-step explanation:
If he runs 2/3 of a mile in 10 minutes all you have to do is multiply it by 3 and you get 6/3 and then you simplify it and end up with 2
3(2x-5)= 21
solve it 2 different ways
plzz hurry i need help
Answer:
x = 6
Step-by-step explanation:
3 (2x - 5) = 21
=> 6x - 15 = 21
=> 6x = 21 + 15
=> 6x = 36
=> x = 36 / 6
=> x = 6
OR
3 (2x - 5) = 21
=> 2x - 5 = 21 / 3
=> 2x - 5 = 7
=> 2x = 7 + 5
=> 2x = 12
=> x = 12 / 2
=> x = 6

A statistical question is a type of question that can't be answered with just one number or value. It has to have different responses for different types of people in different situations. An example of a statistical question is "What do you do afterschool?" because every person does different things afterschool. The only question that has different responses for different people is the first one, "What is your favorite subject this year?".
