You need to wrap a present that you will put inside a cylindrical container. You’ll need to know how much will fit in the conta

nirvana33 [79]

Answer:

149.28 sq. inches

137.5 cubic inches.

Step-by-step explanation:

The cylindrical container has length or height (h) 7 inches and has a diameter of 5 inches i.e. radius (r) 2.5 inches.

Now, total surface area of the container = $2\pi r^{2} + 2\pi rh$

= $\frac{2 \times 22 \times (2.5)^{2} }{7} + \frac{2 \times 22 \times 2.5 \times 7}{7}$

= 39.28 + 110

= 149.28 sq. inches (Answer)

Again the volume of the container will be $\pi r^{2}h$

= $\frac{22 \times (2.5)^{2} \times 7}{7}$

= 137.5 cubic inches. (Answer)

If cot theta = 3/2, what is the value of csc theta?

Arturiano [62]

The value of csc theta is $\frac{3. 61}{2}$

<h3>How to determine the value</h3>

It is important to note that the ratio for cot is given as;

Cot theta = adjacent/opposite

cosec theta = hypotenuse/opposite

If cot theta = 3/2, then

Adjacent = 3

Opposite = 2

Using Pythagoras theorem, we have

Hypotenuse square = opposite + adjacent square

$H = \sqrt{2^2 + 3^2}$

$H = \sqrt{4 + 9}$

$H = 3. 61$

Cosec theta = $\frac{3. 61}{2}$

Thus, the value of csc theta is $\frac{3. 61}{2}$

Find the area of the triangle below. Show as much work as possible. Label your answer appropriately.

Dmitry [639]

Answer:

$Area=\frac{5}{12}x^2$

Step-by-step explanation:

The area of a triangle is given by:

$Area=\frac{1}{2}*base*height$

From the diagram $base=\frac{5}{6}x,and,height=x$

We substitute into the formula to get:

$Area=\frac{1}{2}*\frac{5}{6}x*x$

This implies that:

$Area=\frac{5}{12}x^2$
