What is the height if the cylinder?

Mathematics
1 answer:
Galina-37 [17]3 years ago
4 0

Answer:

13 mm

Step-by-step explanation:

we use the cylinder surface area formula to find the height.

SA = 2πrh + 2πr²    we adjust the formula for h

SA - 2πr² / 2πr = h   Now we can plug in the numbers

(715.92 - 2 * 3.14 * 6²) / 2 * 3.14 * 6

h = 13 mm

Polynomials are mathematical expressions involving variables raised with non-negative integers and coefficients. The polynomial is x³- 7x² - 6x + 72.

<h3>What is a polynomial?</h3>

Polynomials are mathematical expressions involving variables raised with non-negative integers and coefficients(constants who are in multiplication with those variables) and constants with only operations of addition, subtraction, multiplication and non-negative exponentiation of variables involved.

The polynomial using the given information can be made as shown below.

Given the zeros of the polynomial are -3, 4, and 6.

P(x) = (x+3)(x-4)(x-6) = x³- 7x² - 6x + 72

To check the end behaviour of the function, the graph of the function can be plotted as shown in the below image.

Hence, the polynomial is x³- 7x² - 6x + 72.

Sonya paid $2.75 per pound for fresh fish last week. This week, she paid a total of $1.20 more when she purchased 3 pounds of fi
telo118 [61]

The price of fish this week is $3.15 per pound

Step-by-step explanation:

We have to find the total price of 3 pound fish for last week

So,

Price of fish per pound = $2.75

Price of 3 pound fish = 2.75 * 3 = $8.25

As she made $1.20 more in total for 3 pound fish this week

Price of 3 pound fish this week = 8.25+1.20 = $9.45

$9.45 is the total price for 3 pound fish this week.

So,

Price per pound this week will be:

=\frac{9.45}{3}\\=3.15

Hence,

The price of fish this week is $3.15 per pound
