<span>Diameter of the sphere = 8 cm.
Therefore, the radius of the sphere = 8/2 = 4 cm
Volume of the sphere = 4/3 * 22/7 * 3 * 3 * 3 cu. cm.
The sphere is beaten and drawn into a wire, the wire is cylinder of the diameter = 0.2 cm
Area of the base of the cylinder = pi * r2 = 22/7 * 0.2 * 0.2 sq. cm
volume of the wire = pi * r2 * I = 22/7 * 0.2 * 0.2 * 1
Therefore, 22/7 * 0.2 * 0.2 * I = 4/3 * 22/7 * 4 * 4 * 4
Therefore I = 4/3 * 22/7 * 4 * 4 * 4 * 7/22 * 1/0.04
I = 256/3 * 1/0.04
I = 2113 cm</span>
Answer:
the correct answer is C
Step-by-step explanation:
first step you change the x and y powers to the square root(showing in the pic).
second the number outside of the parenthesis times the numbers inside the parenthesis and then you just figure it out how it works...

Answer:
3rd angle of a triangle = x = 75°
Step-by-step explanation:
1st angle of a triangle = 50°
2nd angle of a triangle = 55°
3rd angle of a triangle = x = ?
We know that sum of three angle of triangle = 180°
1st angle of a triangle + 2nd angle of a triangle + 3rd angle of a triangle = 180°
50° + 55° + x = 180°
105° + x = 180°
x = 180° - 105°
x = 75°
3rd angle of a triangle = x = 75°
