Hey there! I'm happy to help!
To find the area of a circle, you square the radius and then multiply by pi (3.14 in our case).
The radius is half of the diameter.
12.6/2=6.3
We square this.
6.3²=39.69
We multiply by 3.14
39.69×3.14=124.6266
We round to the nearest hundredth, giving us an area of 124.63 in².
Now you can find the area of a circle! Have a wonderful day! :D
Answer:
47.88milliliters
Step-by-step explanation:
Given data
Total amount of the solution= 342 milliliters
14% is acid
Hence the amount of acid
=14/100* 342
=0.14* 342
=47.88milliliters
Therefore there are 47.88milliliters of acid
Answer:
I think it's -6x-18, this queston uses distributive property, so you must multiply each term inside the parenthesis to the number outside the parenthesis.
187 centimeters is 1.87 meters
Just turn the percentage to a decimal. 145% becomes 1.45. Then add 1.00 to 1.45. 1 + 1.45 = 2.45
Then multiply. 2.45 * 340 = 833
