A cylinder has a radius of 30 ft and a height of 19 ft. What is the exact surface area of the cylinder?

Answers

Answer 1

Answer: $A=2\pi r(r+h)\n A=2\pi\cdot30\cdot(30+19)\n A=60\pi\cdot49\n A=2940\pi\hbox{ ft}^2$

Answer 2

Answer: $SA=2(pi)rh+2(pi)r^2$

$SA=2(pi)(30)(19)+2(pi)(30^2)$

$SA=2(pi)(30)(19)+2(pi)(900)$

$SA=3581.3+5654.7$

$SA=9236$

9236 square feet

What is the sum of the quotients of 25x^2/5x and the quotient of 8x^2/x

Answers

If you would like to solve (25 * x^2) / (5 * x) + (8 * x^2) / x, you can calculate this using the following steps:

(25 * x^2) / (5 * x) + (8 * x^2) / x = 5 * x + 8 * x = 13 * x

The correct result would be 13 * x.

A kite has diagonals 5.3 ft and 6 ft. What is the area of the kite? A. 5.65 ft². B. 15.9 ft². C. 31.8 ft². D. 22.6 ft²

Answers

Answer: The area of the kite is 15.9 sq. ft.

Step-by-step explanation: Given that a kite has diagonals of lengths 5.3 ft and 6 ft.

We are to find the area of the kite.

We know that the area of a kite having diagonals of length 'p' units and 'q' units is

$A=(p* q)/(2).$

Here, p = 5.3 ft and q = 6 ft.

Therefore, the area of the kite will be

$A(p* q)/(2)=(5.3* 6)/(2)=5.3* 3=15.9~\textup{sq. ft}.$

Thus, the correct option is (B) 15.9 sq. ft.

look at diagram to understand the soluiton

A=(1/2)ab where a is one diagonal and b is the other
A=(1/2)(5.3)(6)
A=(3)(5.3)
A=15.9
B is answer

What is the difference of 1,289 and 943?

Answers

First last number should be subtracted.
9 - 3 = 6

The second last
8 - 4 = 4

Then first number
2-9 = ?
Since it can't be divided, we have to borrow 10 from the previous number.
12-9 = 3

So the answer is,

Simplify the equation 815 = 3x

Answers

Answer:

271.6 or 272

Step-by-step explanation:

815 is being times by 3

so we do the opposite

815/3 on both sides

3x/3=0

drop the x

then do 815/3

= x= 271.6 or 272

Final answer:

To simplify the equation 815 = 3x, divide both sides of the equation by 3 to isolate the variable x. The solution to the equation is x = 271.

Explanation:

To simplify the equation 815 = 3x, we need to isolate the variable x on one side of the equation.

To do this, we divide both sides of the equation by 3 to cancel out the coefficient of x.

This gives us x = 815/3. Performing the division, we get x = 271.

Therefore, the solution to the equation is x = 271.
