<h3>
Answer: 23.13 square meters</h3>
===============================================================
Explanation:
The top and bottom semicircles can be joined to form a full circle. The same can be said about the left and right semicircles. Each circle has diameter 3 and radius 1.5
The area of one circle is
A = pi*r^2
A = 3.14*(1.5)^2
A = 7.065
So two circles doubles to 2*7.065 = 14.13 square meters in area.
Then the last step is to add on the area of the 3 by 3 square (area 3*3 = 9) to get 14.13+9 = 23.13
This area is approximate because pi = 3.14 is approximate. Use more decimal digits in pi to get a more accurate area. However, your teacher wants you to use this specific value so it's best to stick with 23.13
Remember that x/4 and 1/4*x is the same thing.
1/4*52 is therefore the same as 52/4. Fractions represent division, so 52 divided by 4 is also correct.
0.25*x is the same as 1/4*x because 1/4=0.25
4% of 52 is incorrect because the decimal form of 4% is 0.04, which is not the same as 0.25
Final answer: B
Answer:
147.67 and 142.50
Step-by-step explanation:
Cents are only two digits after the decimal, aka hundredths. So, you have to round each number to the hundredth.
Answer:
1/ 6
Step-by-step explanation:
Answer: a) Georgia, b) 120 words
Step-by-step explanation:
We can calculate how many words they each wrote by multiplying their time and the rate at which they write words.
Richard: 45*16 = 720 words total
Georgia: 70*12 = 840 words total.
Therefore, Georgia wrote 120 more words.
