Answer:
30.2 aka C
Step-by-step explanation:
The formula for the area of a circle is A = pir^2. Knowing this we can create the equation A = 3.14(3.1)^2. Following PEMDAS square 3.1 to get 9.61. Then you multiply 9.61 with 3.14 to get 30.1754. When you round to the nearest tenth you get 30.2.
Um not really a specific enough question for a good answer, but I'll give it a go
all you have to do is use long division and divide the numerator by the denominator (top by bottom)
most often the result will not be pretty so round appropriately (i recommend tenths or hundredths)
for exampe
25/11
use some handy division skills, and you'll get about 2.27
note that improper fractions mean that the decimal form will always be greater than 1, or less than -1
<span>the area of Alaska - 1 700 000 square kilometers
and we are told that the land area of Florida is 1/10th the size of Alaska. Therefore land area of Florida is equal to 1/10th of 1 700 000
that's 1 700 000 / 10 = 170 000 km</span>²<span>
therefore land area of Florida is 170 000 km</span>²
1/5 (18-11) I believe this is what you mean?
4-1 would <span>have the difference of 1 + 4</span>
