Which equation can be used to find the surface area of the cylinder?

Mathematics
1 answer:
miss Akunina [59]3 years ago
7 0

Answer:

The fourth one

Step-by-step explanation:

Surface area of a cylinder: SA=2\pi rh+2\pi r^2

where r = radius and h = height

We have a given height of 14cm and a given diameter of 6cm

We need the radius, not the diameter

To convert diameter to radius we simply divide by 2

6 / 2 = 3

so R = 3

We now plug in the given values into the formula

SA=2\pi (3)(14)+2\pi (3)^2

This equation matches with answer choice D

Answer:

b, c, a

Step-by-step explanation:

In a triangle, the largest angle is opposite the longest side. The smallest angle is opposite the shortest side.

This triangle has 2 given angles, 50° and 60°.

We can find the measure of the third angle, x.

50 + 60 + x = 180

x + 110 = 180

x = 70

The three angles have measures 50°, 60°, and 70°.

The shortest side is opposite the smallest angle. That is side a.

The longest side is opposite the largest angle. That is side b.

The order from longest to shortest is

b, c, a
