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.
Answer:
260.55cm
Step-by-step explanation:
[3.14(6^2)]/2+(12x12)+60 use Pythagorean theorem to the shortest leg of the 2 triangles {12^2+b^2=13^2) b=5, 5*12 60/2=30x2 = 60 all of it added up is 202
Answer:
3x + y = 20
Step-by-step explanation:
The equation of line passing through two points is determined by formula:

Here, (x₁ , y₁) = (4, 8)
and (x₂, y₂) = (6, 2)
Putting these value in above formula. We get,
⇒ 
⇒ ( y - 8) = -3 (x - 4)
⇒ y - 8 = -3x + 12
⇒ 3x + y = 20
which is required equation.
