Answer:
Radius of the sphere = r
<u>Volume of sphere:</u>
Radius of the hemisphere = 2r
<u>Volume of the hemisphere:</u>
- V₂ = 1/2×4/3×π(2r)³ = 1/2×8×4/3πr³ = 4V₁
The volume of the hemisphere is 4 times greater than the volume of the sphere
Answer:
congruency means that the size and shape must be exactly the same in the figures that are compared. A triangle cannot be congruent to a quadrilateral because it has three sides whereas a quadrilateral has four. An isosceles triangle cannot be congruent to a non isosceles triangle because the sides would be different lengths.

7x+12+63=180
8x+12=180
Subtract 12 from both sides
8x= 168
=c=21
10x-40=50
Add 40 to both sides
10x=90
X=9
4x+72+2x-12=180
6x +60 =180
Subtract 60 from both sides
6x=120
X=20
