What is the surface area of the cylinder with a height of 3 m and radius of 4 m? Round your answer to the nearest thousandth.

IgorLugansk [536]

Answer:

The surface area of the cylinder is of 131.947 square meters.

Step-by-step explanation:

Surface area of a cylinder:

The surface area of a cylinder of height h and radius r is given by the following equation:

$S_a = 2\pi r(h+r)$

What is the surface area of the cylinder with a height of 3 m and radius of 4 m?

$h = 3, r = 4$ .

$S_a = 2\pi r(h+r) = 2\pi(3)(3+4) = 42\pi = 131.947$

Height and radius are in meters, so the surface area will be in square meters.

The surface area of the cylinder is of 131.947 square meters.

Determine whether the two triangles are similar and, if they are similar, state a reason.

aleksley [76]

Answer:

Step-by-step explanation:

By triangle sum theorem,

Sum of interior angles of a triangle is 180°.

Therefore, measure of third angle in the larger triangle = 180° - (35° + 120°) = 25°

Similarly, measure of third angle in the smaller triangle = 180° - (25° + 120°)

= 35°

Since, measure of interior angles of larger triangle is equal to the measure of smaller triangle,

Both the triangles will be similar by AA property of similarity.

on selling a fan for rupees 4700 A shopkeeper loses 6% at what price must he sell it to gain 6 percentage

Sliva [168]

Given:

Selling price of a fan = Rs.4700

Loss percent = 6%

To find:

The price at which he must sell it to gain 6 percentage.

Solution:

Let x be the cost price of the fan.

Loss percent = 6%

Selling price = Cost price - 6% of cost price

$S.P.=x-\dfrac{6}{100}x$

$S.P.=x-0.06x$

$S.P.=0.94x$

Selling price of a fan = Rs.4700

$4700=0.94x$

$\dfrac{4700}{0.94}=x$

$5000=x$

So, the cost price of the fan is Rs.5000.

Now, he need to sell this fan in 6% gain.

Selling price = Cost price + 6% of cost price

$S.P.=5000+\dfrac{6}{100}\times 5000$

$S.P.=5000+300$

$S.P.=5300$

Therefore, he must sell it for Rs.5300 to gain 6 percentage.
