Answer:
12 pi
Step-by-step explanation:
volume of sphere = 4/3 pi r2
4/3 pi 3 x 3
12 pi unit square
x = 5
ABC is an isosceles triangle
So
<A = <C = 73
<B = 180 - 2 * 73
<B = 180 - 146
<B = 34
Given <B = 6x +4
6x + 4 = 34
6x = 30
2x - 12 + 6 = 4x - 4
2x- 6 = 4x - 4
-6 +4 = 4x - 2x
-2 = 2x
x= -2/2
x = -1
As we know,
now, let's plug the given values to find a² + b²
