The area of a circle A equals either:
πr² or πd²/4
96 = πd²/4 => d = 11 inches
The diameter of the second circle equals :
11*1.5 = 16.5 inches
The area equals: π(16.5)²/4 = 214 square inches
Good luck
The surface area formula for any sphere is 4(pi)(radius)^2
The radius is half of the diameter.
18.6 / 2 = 9.3
So, plug into the formula and solve.
4(3.14)(9.3)^2 = 1086.3 mm^2
We know that in order to find the point (-3,-7), we must first go to the left on the x-axis 3 units from the origin, and then directly down on the y-axis 7 units. Using the attached image, we can see that this would then put us into the third quadrant or Quadrant III. Therefore, the answer is D) The point is in the third quadrant.
