Answer:
13.7 ft^2
Step-by-step explanation:
1. Find the radius of the semicircle by dividing the diameter by 2 to get 1.8
2. Find the area of the semicircle. Do this by substituting the equation to find the area of a semicircle with the numbers given and solving. 3.14(1.8^2)/2 = 5.0868
3. Find the area of the triangle. Do this by substituting the equation to find the area of a semicircle with the numbers given and solving. 1/2(3.6*4.8) = 8.64
4. Add both your numbers together to get 13.7268
5. Round to the nearest 10th to get 13.7 ft^2
Answer:
Step-by-step explanation:
Look at the 3rd decimal digit (the digit after the hundredths).
- if it is the digit is less than 5 then round the number down by taking away the decimal point of the number after the 2nd decimal place;
- However if it is 5 or more then round the number up by adding one on to the hundredths digit and removing the rest of the decimal part of the number after it
For example,4.749 rounds up to 4.75 because the 3rd decimal digit is a 9.
I hope this helps ^^
