Answer:

360 pi in ^3

Step-by-step explanation:

The volume of a cylinder is given by

V = pi r^2 h

We know the diameter is 12 so the radius is 1/2 the diameter

r = d/2 = 12/2 = 6

V = pi (6)^2 * 10

V = pi (36)*10

V = 360 pi in ^3

We can approximate pi by 3.14

V =1130.4 in ^3

Or we can approximate pi by using the pi button

V =1130.973355 in ^3

Question 28 of 30Calculate the surface area in square feet of a box that measures 13 inches inlength, 11 inches in width, and 11

KATRIN_1 [288]

ANSWER:

5.65 ft²

STEP-BY-STEP EXPLANATION:

We have the following measures:

Length (l) = 13 inches

Width (w) = 11 inches

Height (h) = 11 inches

We can determine the surface area as follows:

$\begin{gathered} A=2\cdot l\cdot w+2\cdot l\cdot h+2\cdot w\cdot h \\ \\ \text{ We replacing:} \\ \\ A=2(13)(11)+2(13)(11)+2(11)(11) \\ \\ A=286+286+242 \\ \\ A=814\text{ in}^2 \\ \\ \text{ Convert inches to feet, knowing that 1 foot is equal to 12 inches} \\ \\ A=814\text{ in}^2\cdot\frac{(1\text{ ft\rparen}^2}{(12\text{ in\rparen}^2} \\ \\ A=5.65\text{ ft}^2 \end{gathered}$

Therefore, the correct answer is 5.65 ft²

the length of the base of an isosceles triangle is x. The length of a leg is 4x-5. The terminator of the triangle is 35. find x.

vodomira [7]

Answer:

x= 5

Step-by-step explanation:

We are given;

Base of the triangle as x
Length of the leg is 4x-5
An isosceles triangle has two equal legs and a base.
The perimeter of the triangle is 35 (spelling mistake in the question)

To get the perimeter of a triangle we add the lengths of all sides of the triangle.

Therefore;

x + 4x-5 + 4x-5 = 35

9x - 10 = 35

9x = 45

x = 5

Thus, the value of x is 5
