Thirty four million two hundred thirty five thousand three hundred forty five
Answer:
Step-by-step explanation:
From the way the answers are presented, it can be seen that x refers to the radius of the base of the cone
radius: 
and we are told that the height is twice the radius, so:
height: 
and now we use the formula to calculate the volume of a cone:
where 
is volume, 
is radius, and 
is the height. and 
is a constant
in this case
so we substitute thisvalues in the formula for the volume:
Rearranging the terms
which is option A.
Answer:
A: 15
Step-by-step explanation:
The angles are opposite to each other.
Vertically opposite angles are equal in size.
Put up an equation and solve for a.
6a + 10 = 3a + 55
Subtract 3a and 10 on both sides.
6a - 3a = 55 - 10
Combining like terms.
3a = 45
Divide both sides by 3.
a = 45/3
a = 15
The value of a is 15.
The statement that correctly describes the product, 5.15 x 6√7, which is 81.7537155..., is <u>A. </u><u>irrational</u>.
<h3>What is an irrational product?</h3>
An irrational number is one that can be written as a decimal, but not as a fraction.
An irrational number has endless non-repeating digits to the right of the decimal point.
The rules for determining if a product is rational or irrational are as follows:
- The product of two rational numbers is rational.
- The product of a rational number and an irrational number is irrational.
- The product of two irrational numbers is irrational.
<h3>Data and Calculations:</h3>
5.15 x 6√7
= 5.15 x 6 x 2.64575...
= 81.7537155...
Thus, the product of 5.15 x 6√7 is irrational because √7 is irrational.

<h3>Complete Question with Answer Options:</h3>
Which of the following correctly describes the product below?
5.15 x 6√7
A. irrational
B. neither rational nor irrational
C. a combination of both rational and irrational
D. rational
Answer:
87
Explanation:
This is an arithmetic sequence with <u>common difference</u>: 7 and <u>first term</u>: 17
Arithmetic sequence:
a + (n - 1)d where n is term position, d is difference, a is first term
17 + (n - 1)7
7n + 10
The eleventh term:
7n + 10
7(11) + 10
77 + 10
87
