2 answers:
Answer:
The answer is 3x3x3.
Step-by-step explanation:
A prime factorization consists in write down a multiplication in prime numbers. In this case we have that Sam sent an email to 3 friends on Monday, then all his friends an email to 3 friends more on Tuesday and the same happen on Wednesday. So this could be write as:
Monday: 3 emails
Tuesday: 9 emails
Wednesday: 27 emails
The question is to write the number of emails sent on Wednesday, so:
Is not enough because it has to be write in prime numbers:
Now the factorization is write in prime numbers. The answer is 3x3x3.

Answer: 113.04 cm³
Step-by-step explanation: To find the volume of a sphere, start with the formula for the volume of a sphere which is shown below.
Here, we are given that our sphere has a radius of 3 centimeters.
So plugging into the formula, we have .
Start by simplifying the exponent.
(3 cm)³ is equal to 3 centimeters · 3 centimeters ·
3 centimeters or 27 cm³.
So we have .
Notice that we can cross-cancel 3 and 27 to 1 and 9.
So we have (4)(9 cm³) which is equal to 36 cm³.
So we have 36π cm³.
So the volume of the sphere is 36π cm³.
Remember that π is approximately equal to 22/7 or 3.14 so we can estimate the value of the volume by plugging in 3.14 for π.
So we have (36)(3.14) which is equal to 113.04 which means
that the volume of approximately equal to 113.04 cm³.
