Answer: 9
Step-by-step explanation: Multiply 3 to itself and you will get nine.
3^2
The midpoint formula is (x1+x2/2, y1+y2/2
so you would do (-5+14)/2=4.5. (-2+12)/2=5
(4.5, 5)
To find the answer you have to find the area of the fountain using A= pi r^2.
=(3.14)(64)
=200.96
Then you have to find the area of the big circle.
=(3.14)(11^2)
=379.94
Then subtract them both (379.94-200.96) and you get the answer 178.98 which can be rounded to 179 aka A.
The formula of a perimeter of a rectangle l × w:
P = 2l + 2w
We have the perimeter P = 76 cm and the length l = 20 cm. Substitute:
76 = 2(20) + 2w
76 = 40 + 2w <em>subtract 40 from both sides</em>
36 = 2w <em>divide both sides by 2</em>
18 = w
Answer: width = 18 cm.
