Find the surface area Sphere: area of the great circle ~ 28.6 in2

1 answer:

6 0

Area of a circle is πr².

Therefore we can get the radius of the great circle (and thus the sphere) by doing √(A / π).

√(28.6 / π) = 3.017 to 3DP.


Surface area of a sphere is 4πr².

4π(3.017)² = 114.4 to 1DP

Solve for x in the triangle

kykrilka [37]

tan(angle) = opposite/adjacent

tan(37) = x/14

14*tan(37) = x

x = 14*tan(37)

x = 10.5497567

x = 10.5

Answer: 10.5

Find the measure of z A. 108 B. 120 C. 135 D. 144

Nostrana [21]

Sum of all interior angles = ( n - 2) x 180

Since Octagon = 8 sides,

Sum of all interior angles = ( 8 - 2) x 180 = 1080

z = 1080 ÷ 8 = 135°

Answer: z = 135°
