Answer:

26.2 inches cubed

Step-by-step explanation:

The volume of a cone is denoted by: V=\frac{1}{3} \pi r^2h, where r is the radius and h is the height.

Here, we are given that the diameter is 5. Remember that the radius is simply 1/2 the diameter, so the radius is r = 5/2 = 2.5. We are also given that the height is h = 4. Plug these into the equation:

V=\frac{1}{3} \pi r^2h

V=\frac{1}{3} *3.14* (2.5^2)*4 ≈ 26.2

Thus, the volume is about 26.2 inches cubed.

Hope this helps!

A teacher Buys tickets for each of my students to visit a museum each student and $6.50 and she spent a total of $182 how many s
vaieri [72.5K]

Answer:

The ticket is bought for 28 students.

Step-by-step explanation:

It is given that the teacher is going to buy museum ticket for each students.

Total money spent = $182

Price of each ticket = $6.50

Let total number of tickets bought = x

We know that to find the total amount of money spent on ticket, we can add price of each ticket (i.e. $6.50) x number of times.

OR

In other words, simply multiply the number of tickets with price of each ticket to find the total money spent.

Total money spent = x \times 6.50

We know that total money spent is $182.

\Rightarrow x \times 6.50 = 182\\\Rightarrow x = \dfrac{182}{6.50}\\\Rightarrow x = 28

The ticket is bought for 28 students

Answer:

see explanation

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan A = \frac{opposite}{adjacent} = \frac{BC}{AC} = \frac{7}{8} , then

∠ A = tan^{-1} (\frac{7}{8} ) ≈ 41° ( to the nearest degree )

The sum of the angles in the triangle = 180° , then

∠ B + 41° + 90° = 180°

∠ B + 131° = 180° ( subtract 131° from both sides )

∠ B = 49°

Using Pythagoras' identity in the right triangle

AB² = BC² + AC² = 7² + 8² = 49 + 64 = 113 ( take square root of both sides )

AB = \sqrt{113} ≈ 10.6 ( to the nearest tenth )
