What is the surface area of this cylinder ?

Lana71 [14]

Answer:

87.92 mm²

Step-by-step explanation:

Given:

Radius of circular base: 2 millimeters
Height of cylinder: 5 millimeters

<u>It should be noted:</u>

Surface area of cylinder: 2πrh + 2πr² (R = Radius; H = Height)

When the measures are substituted, we get the following expression:

⇒ 2π(2)(5) + 2π(2)²

Multiply the constants and substitute π as 3.14.

⇒ 20π + 2π(4)
⇒ 20π + 8π
⇒ 20(3.14) + 8(3.14)

Finally, simplify the expression to determine the surface area.

⇒ 20(3.14) + 8(3.14)
⇒ 62.8 + 25.12
⇒ 87.92 mm²

Given line segment AB, the coordinates of A are (3,-5) and the coordinates midpoint are (5,-1), what are the coordinates for B?

dsp73

Answer:

Step-by-step explanation:

Point P(5, -1) being the midpoint of AB means that $x_P-x_A=x_B-x_P$

$5-3=x_B-5\\\\2+5=x_B\\\\x_B=7$

and $y_P-y_A=y_B-y_P$

$-1-(-5)=y_B-(-1)\\\\-1+5=y_B+1\\\\y_B=3$
