Answer:
The diameter will be given by 50 cm ÷ 3.142 = 15.9134 cm
The radius will be 15.9134 ÷2 = 7.9567 cm or about 7.96 cm
The area of a circle is given by \pi × square of radius
Area = 3.142 × 7.96×7.96 = 199.0821 square cm
Answer:
Im on the same question so dont copy word for word
Step-by-step explanation:
The first error he made is that he didn't do the right steps in order to find the area of the two triangles. Instead he should have done 0.5 X 16 X 15 X 2= 240
Then the area for the three rectangles should be 16 X 8 + 17 x 8 + 17 X 8 = 400
If you add it all together, the surface area is actually 640 square meters.
Answer:
A. 30/100
Step-by-step explanation:
All you have to do is divide the numerator by the denominator and then multiply that result with 100 like so:
(Numerator/Denominator)*100
When you enter 30/100 into the above formula, you get (30/100)*100 which calculates to:
30%
Good Luck!
Answer:the library checks out 2 times more fiction books than the nonfiction books.
Step-by-step explanation:
Total number of fiction books that the Library checks out in an hour is 4.
Total number of non fiction books that the Library checks out in an hour is 2.
To determine how many times more fiction books that they check out than the nonfiction books, we would divide the total number of fiction books that the Library checks out in an hour by the total number of non fiction books that the Library checks out in an hour. It becomes
4/2 = 2
