In the standard (x,y) coordinate plane, what is the area of the circle x^2 + y^2 =169?

schepotkina [342]

Answer:

169π

Step-by-step explanation:

circle eq: (x-a)²+(y-b)²=r², where (a,b) is center and r is radius

r²=169

r = ±13

since a radius length must be positive, r = +13, not -13

A of circle: πr²

r = 13

169π

given that the circle eq has r², you could've noticed that you can take the constant in the circle eq and multiply that by π to get the same answer

Find the volume of the composite solid. Round your<br> anwser to the nearest hundredth.

Lelu [443]

Answer:

226.19 $cm^{3}$

Step-by-step explanation:

Vol. of cone = Bh/3 where B is the area of the base(circle) and h is the height of the cone.

r = 3 h = 3

V = $\frac{\pi *3^{2}*3 }{3}$ = 9π

Vol. of the cylinder = Bh where B is the base(circle) and h is the height of the cylinder.

r = 3 h = 10 - 3 = 7

V = $\pi *3^{2} * 7$ = 63π

Total volume = 9π + 63π = 72π = 72(3.1416....) = 226.19
