Answer:

The surface area of the cylinder is about 954.56 square inches.

Step-by-step explanation:

The total surface area of a cylinder is given by the formula:

$SA=2\pi r^2 + 2\pi rh$

Here, we are given that the radius is 8 inches and that the height is 11 inches. We are also using 3.14 for π. So, substitute:

$SA\approx 2(3.14)(8)^2+2(3.14)(8)(11)$

Use a calculator:

$SA\approx 954.56\text{ in}^2$

The surface area of the cylinder is about 954.56 square inches.

Write an equation to represent the following statement.<br> 33 is 15 less than k.

lianna [129]

Answer:

33 = k - 15

Step-by-step explanation:

This question can be solved but if your asking about equation 33 = k - 15 is it, because 33 is the total and 15 is less than k, whenever you see less than the number before is always the number telling the other number to subtract, such as 44 is 16 less than a number, the answer will be 44 = x - 16.

Find the value of x. If necessary, round to the nearest tenth.

Ghella [55]

Answer:

x = 10.3 in

Step-by-step explanation:

To find the value of a, use the area formula for a triangle. The formula is A = 1/2 *b*h. Here b = x and h= x. The formula becomes A = 1/2 *x². Substitute A = 53 and solve for x by using inverse operations.

A = 1/2x²

53 = 1/2x²

106 = x²

√106 = x

10.3 = x

enot [183]

Given :

Number of hours studied daily , $T=5\dfrac{2}{3}$ .

Time given for science and mathematics is , $t=2\dfrac{4}{2}$ .

To Find :

How much time does she devote for other subjects .

Solution :

Let , time devote for other student is x .

So , Time left for other subject = Total time - Time taken by science and mathematics .

$x=T-t\\\\x=5\dfrac{2}{3}-2\dfrac{4}{2}\\\\x=\dfrac{(5\times 3)+2}{3}- \dfrac{(2\times 2 )+4}{2}\\\\x=\dfrac{17}{3}-4\\\\x=\dfrac{17-(4\times 3)}{3}\\\\x=\dfrac{5}{3}=1\dfrac{2}{3}$

Therefore , time devote for other subject is $1\dfrac{2}{3}$ hours .

Hence , this is the required solution .
