The point (0, 5) lies on circle A with the center at the origin. Does the point (0, −5 ) lie on the circle? A. Yes, because both
mars1129 [50]
<h3>Answer:</h3>

A. Yes, because both points are equidistant from the center of the circle.

<h3>Step-by-step explanation:</h3>

The point (0, 5) is 5 units from the point (0, 0).

The point (0, -5) is 5 units from the point (0, 0).

The given points are equidistant from the circle center at (0, 0), so both will lie on the circle—along with any other points that are 5 units from (0, 0).

Find the surface areas of the figures below. I don't need the work, just the answers.
kow [346]

Hello!

The surface area of a sphere is found by using the formula: SA = 4πr².

Figure 1

In the first figure, the radius is given which is 18 meters. With that, we can substitute the value of the radius into the formula and solve.

SA = 4π(18)²

SA = 4(324)π

SA = 1296π, 4071.50 (multiplied by π), 4069.44 (multiplied by 3.14)

Therefore, the surface area of figure one is 1296π m².

Figure 2

In the second figure, the diameter of the circle is given. The radius is half the diameter, so to find the radius, you need to divide the diameter by 2.

14 mm / 2 = 7 mm

With that, we can find the surface area of figure two, using the formula.

SA = 4π(7)²

SA = 4(49)π

SA = 196π, 615.75 (multiplied by π), 615.44 (multiplied by 3.14)

Therefore, the surface area of figure two is 196π mm².
