Step-by-step explanation:
The surface area of a sphere is...
A = 4 pi r^2
We would find the radius in which we make this an equation of the radius.
r = (sqrt A pi) / 2 pi
Once we identify r we would then input the radius in the equation for the volume of a sphere....
<span>V = 4/3 pi r^3</span>
Answer:
Angle I = 90 degrees
Angle J = 61 degrees
Angle K = 29 degrees
Step-by-step explanation:
Angle I is given
We know that the angles in all triangles add up to 180. Since we are given that angle I is equal to 90 degrees, we now know that angle J + angle K = 90 degrees:
(5x+26) + (2x+15) = 90
Solve for X:
7x + 41 = 90
7x = 49
x = 7
Angle J = (5x + 26) = (5(7) + 26) = 61
Angle K = (2x + 15) = (2(7) + 15) = 29
Checking your work: 61 + 29 = 90
