A=pR^2-2pr^2, since R=15 and r=7.5
A=225p-112.5p
A=112.5p
A≈353.25 ft^2
5/8, 1/9....these are in simplified form because they cant be reduced
12/15 simplifies to 4/5
4/8 simplifies to 1/2
9/18 simplifies to 1/2
B. 195
It’s B because if you divide 584 with 3 it equals 194.66 but you round up and it becomes 195.
Answer:
81 square inches.
Step-by-step explanation:
Draw a diagram to represent what you know.
You don't know the values of the lengths so represent them algebraically.
You know the perimeter is 45 inches and that the perimeter is calculated by the sum of all of the sides of a shape.
You can rearrange to find the value of a side you've denoted as some unknown variable.
The area is given by the product of the sides. Express this algebraically and then input the value you found.
