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.
