Answer:
12) 154 squared meters
13) 307 cm^2
Step-by-step explanation:
12) A circle has area pi*r^2
r is half the diameter so half of 14 is 7
pi in this case is 22/7
A=22/7 * (7)^2
A=22/7 * 49
A=22 *49/7
A=22 *7
A=154 squared meters
13) Area of rectangle is 10(18)=180
Area of half a circle is .5*pi*r^2=.5*pi*9^2
Adding the two areas together would result in a total area of 307.2 squared centimeters

Answer:
80%
Step-by-step explanation:
Bugs are 4/5, but you can't do that as a precentage. You then multiply 5 x 2 to get 10, and 4 x 2 to get 8. Then, you multiply both by 10, and then you take out the fraction and replace it with a precent sign. Then you get your answer, 80%.
