We have that the formula of the volume of a Sphere is
a.
the radius of the sphere is r=2
the volume will be
b.
the radius of the sphere is r=4
the volume will be
c. as we can see the radius of the sphere b, is twice the radius of sphere a, but as we can see because we calculated the volume of spheres, the volume of the sphere b is much bigger than the twice of the volume of the sphere a. It is because we don't have a linear relationship because we have an exponent 3 in the radius in the formula of the volume
Answer:
Step-by-step explanation:
This question is a bit sloppy. In higher math courses it would not be permitted. I'll give you the general rule that applies to this question -- sort of.
If you have a triangle that hast angles of 100 50 and 30
The largest side will be opposite the 100 degree angle.
The smallest side will be opposite the 30 degree angle.
So for the question, you are intended to say that CD > AB because CD is opposite a 43 degree angle and AB is opposite a 40 degree angle.
So the answer is Since 43 > 40 then CD>AB
What they said was correct!!

Step-by-step explanation:
well, I see one large rectangle (20×6), and 2 small triangles with their horizontal sides being (20-8-6)/2 = 3 m. and their vertical joined side being 10-6 = 4 m.
the total area is simply the sum of the rectangle and the 2 triangles.
the rectangle is
20×6 = 120 m²
each triangle is
4×3/2 = 2×3 = 6 m²
we have 2 of them, so their combined area is 2×6 = 12 m².
the total area is
120 + 12 = 132 m²
