I would be glad to help you! I will solve through 3 to get you started.
This is a very important concept, so it would be helpful if you learn it on your own.
C= 2* pi* r
1. The radius is 5 cm. 5 cm represents r in the equation.
C= 2* 3.14 (or pi)* 5
Multiply it by using a calculator.
My answer was 31.4.
Let's try the second one.
2. The diameter is 9. Have of the diameter is the radius.
9/2= 4.5
Plug it into the equation.
C= 2*3.14*4.5
I got 28.26
One more.
Plug it into the equation.
C= 2*3.14*5.6
35.17 was my answer.
Make sure to add the end signs to you answer, ft, cm, meter, etc.
Let me know if you need more help.
Brainliest answer is always appreciated.
Answer:
$59
Step-by-step explanation:
You first need to find what 18, 27, and 36 can all fit into.
108 is divisible by each of these values:
108/18= 6 108/27=4 108/36=3
This will equate to how many packages of each item you will need:
6 pkgs of Plates, 4 pkgs of Cups, 3 pkgs of Forks
6*$2=12 4*$8=32 3*$5=15
Add these values to find total: 12+32+15=$59
Answer:
x = 28⁰
Step-by-step explanation:
sum of the angles of a triangle = 180⁰
∠A + ∠B + ∠C = 180⁰
∠A = 5x - 60⁰
∠B = 2x + 40⁰
∠C = 3x - 80⁰
<h2>:- Solution</h2>
∠A + ∠B + ∠C = 180⁰
5x - 60 + 2x + 40 + 3x - 80 = 180⁰
5x + 2x + 3x - 60 + 40 - 80 = 180⁰
10x - 20 - 80 = 180⁰
10x - 100 = 180⁰
10x = 180 + 100⁰
10x = 280⁰
x = 280⁰/10
x = 28
_______________________
Always read the question very carefully as it contains a lot of vital information's. Based on those information's the answer to the question can be easily deduced.
Total number of questions given in a Chinese test = 40
Percentage of questions incorrectly answered by Kara = 10%
Then
Number of questions incorrectly answered by Kara = (10/100) * 40
= 4
Then
The total number of questions correctly answered by Kara = 40 - 4
= 36
From the above deduction we can clearly see that Kara answered 36 questions correctly among the total of 40 Chinese questions that were given.
