Answer:
1; 31.2 2; 12.4 3; 30.8 4; 118.4 5; 16.53 (i ran out of time or else i wouldve finished, just use google for answers! ^_^)
done the rest, just Step-by-step explanation:
To find the difference, we are going to destroy the parenthesis first, and then, we are going to perform the operations. Remember that to destroy a parenthesis preceded by a negative sign (-), you should change the signs of the factors inside the parenthesis:
Now we can factor both numerator and denominator and simplify:
We can conclude that the difference in simplest form is:
<u>Given</u>:
Given that the diameter of the hemisphere is 12.6 cm
The radius of the hemisphere is given by
We need to determine the volume of the hemisphere.
<u>Volume of the hemisphere:</u>
Let us determine the volume of the hemisphere.
The volume of the hemisphere can be determined using the formula,
Substituting the values, r = 6.3 and π = 3.14, we have;
Simplifying the values, we have;
Dividing, we have;
Rounding off to the nearest tenth, we get;
Thus, the volume of the hemisphere is 523.5 cm³
The types of radiation are
Alpha
Beta
Gamma
Alpha radiation is the energy carried by fast moving helium atoms.
Beta radiation is the energy of electrons released from atoms.
Gamma radiation is the energy released by radioactive or unstable atoms.
