Awire extends from a building at a point 18 meters up and makes a 65 angle with the ground. what is the length of the wire to the nearest hundredth of a meter?

The length of the wire is 19.86 meters

Step-by-step explanation:

We can find the length of the cable using a right triangle like the one shown in the figure.

In this triangle, the opposite side of the 65 ° angle represents the height from the start of the cable to the end point. If we call b to this opposite side, then:

The length of the cable is the hypotenuse h of this triangle

We know that by definition the sine of an angle is:

So:

to the nearest hundredth.

Step-by-step explanation:

The building, the wire and the ground creates a right triangle.

The point 18 meters up the building is the side opposite to the 65 degree angle.

We can use the sine ratio to find the value of the length of the wire which is the hypotenuse.

Let, the length of the wire be units.

to the nearest hundredth.

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
