Answer:
X=11
Step-by-step explanation:
11-7=4 5(4)=20 So X equals 11
As we know from geometry, the volume of any given sphere is
V = 4/3*πr³
Since a hemisphere is half of any given sphere, its volume should be
V = 4/3*πr³ ÷ 2
V = 2/3*πr³
This will be our working equation for finding the volume of hemisphere. Since r is already given to be 5 units, we substitute this to the working equation:
V = 2/3*π(5)³
V = 261.8 cubic units

Answer:
8
Step-by-step explanation:
0.25 * 32=8, meaning that 8 of the students are boys. 32 is the whole, because it is the entire class. Hope this helps!
Answer:
Each cube with side lengths of 1/4 has a volume of (1/4)3 which means each cube's volume is 0.015625 cubic units. To find how many cubes are needed to fill the prism, divide 3 cubic units by 0.015625 cubic units. Your answer will be 192 cubes.
