Lateral, means 'side'. So basically they want us to find out the surface area of the can, excluding the top and the bottom.

To solve for the lateral surface area, we multiply the height of the paint can by the circumference of the top circle. We know the height is 7 1/2 in but we need to solve for the circumference.

C=πd
C=6 5/8π in

Surface Area=7 1/2*6 5/8π=49 11/16π in² or 156.097in²

Answer= 49 11/16π in² or 156.097in²

First you find the radius. Pi r squared. Then you multiply the radius by the height

The equation of the piecewise function f(x) is below. What is the value of f(3)?

JulijaS [17]

Option B: 5 is the value of f(3)

Explanation:

The equation of the piecewise function is given by

$f(x)=\left\{\begin{aligned}-x^{2}, & x$

We need to find the value of $f(3)$

The value of the function f can be determined when $x=3$ by identifying in which interval does the value of $x=3$ lie in the piecewise function.

Thus, $x=3$ lies in the interval $x\geq 0$ , the function f is given by

$f(x)=x+2$

Substituting $x=3$ in the function $f(x)=x+2$ , we get,

$f(3)=3+2$

$f(3)=5$

Thus, the value of $f(3)$ is 5.

Therefore, Option B is the correct answer.

Hiiio!!Can someone please help me ❤️:D

Delvig [45]

Answer:

Step-by-step explanation:

ratio of 216 : 64

bigger is 20 inches

so divide 20 by 216... to find the unit.. then multiply that by 64 to find the size of the other

20/216 = 0.0925925

0.0925925 * 64 =5.9259"

so about 6 inches

Point M is the midpoint of AB . Through point M a line segment XY is drawn, so that both XA and YB are perpendicular to AB . Pro

GaryK [48]

Answer:

See the proof below

Step-by-step explanation:

Let the line AB be a straight line on the parallelogram.

A dissection of the line (using the perpendicular line X) gives:

AY ≅ BX

Another way will be using the angles.

The angles are equal - vertically opposite angles

Hence the line AY ≅ BX (Proved)
