Ok so first, you add $8.50, $10.25, and $2.25 to get the total bill of $21. Since 3 people are splitting the bill equally, divide $21 by 3 to get $7. Hope this is helpful!

What is the total surface area of the cylinder?
a_sh-v [17]

Answer:

Option A = 113.04in^2

Step-by-step explanation:

Question: What is the total surface area of the cylinder? If the radius is 2in and height is 7in.

A) 113.04 in.2

B) 100.48 in.2

C) 131.88 in.2

D) 69.08 in.2

Solution:

Total surface area of a cylinder = 2πr^2 + 2πrh

r = radius = 2in

h = height = 7in

Let π = 3.14

Total surface area of the cylinder =

2×π×2^2 + 2×π×2×7

= 8π + π×28

= 8×3.14 + 3.14×28

Total surface area of the cylinder = 113.04in^2

=113.04in^2 (option A)

Part 1:
AURORKA [14]

The following are the answers to the questions presented:

Part 1:

Vertex: <span>(<span><span>−3</span>/ 2</span>,<span> 11/2</span>)</span>

Axis of symmetry = x = -3/2

Domain = all real numbers

Range = <span>y </span><span>≤ </span>11/2

Part 2:

A quadratic equation is symmetrical around its vertex. The equation for the axis of symmetry is x = -3/2 since the equation is in terms of x. Since no value of x is undefined, then the domain of the equation is clearly all real numbers. Since the value of “a” is negative, then that means the y coordinate of the vertex is the maximum value so the range will never get above 11/2. I am hoping that these answers have satisfied your queries and it will be able to help you in your endeavors, and if you would like, feel free to ask another question.

Find the equation of the line that goes through ( 2, 4 ) and ( 4, 6 ).
Mrrafil [7]

Answer:

y=x+2

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(6-4)/(4-2)

m=2/2

m=1

y-y1=m(x-x1)

y-4=1(x-2)

y=x-2+4

y=x+2
