The formula of a volume of a sphere:
R - radius
We have R = 3.15 m. Substitute:
4.
The formula of a volume of a cone:
r - radius
H - height
We have 2r = 11.6 → r = 5.8 and H = x. Substitute:

The formula of a volume of a cube:
s - edge
We have s = 1.02 in. Substitute:
Answer:
Simplify the problems first
Step-by-step explanation:
Before you can convert it to scientific notation, you should simplify it first.
#1 for example:
Use PEMDAS to solve the equation:
So, now we have a super big number. To write it in scientific notation, put a decimal place in the number before the zeroes start. It would be 
since there are 11 places after the decimal.

<u>Answer:</u>
The measure of the supplement of an angle is 20° More than three times the measure of the original angle. The angles are 40 degrees and 140 degrees.
<u>Solution:</u>
Given, The measure of the supplement of an angle is 20° More than three times the measure of the original angle.
We have to Find the measures of the angles.
Let the original angle be n degrees.
We know that, sum of supplementary angles is 180, then, supplementary angle of n will be 180 – n.
Now according to the given information, 180 – n = 20 + 3 x n
180 – n = 20 + 3n
3n + n = 180 – 20
4n = 160
n = 40
Then, supplementary angle is 180 – 40 = 140 degrees.
Hence, the measures of two supplementary angles are 40 degrees and 140 degrees.
The term axiom is used to describe statements that is taken to be true and can not be proofed. The axioms are taken as the most true statements (more true than theorems and conjectures) and are used as a starting points for other proofs and argumentation. Proof is <span>the sufficient evidence for the truth of a statement. So, in order to obtain a proof several true statements (axioms) must be used. </span>
