Answer: the height of the cylinder is 24

Step-by-step explanation:

The formula for determining the total surface area of a cylinder is expressed as

Total surface area = 2πr² + 2πrh

Where

r represents the radius of the cylinder.

h represents the height of the cylinder.

π is a constant whose value is 3.14

From the information given,

Total surface area = 56π

radius = 2

Therefore,

56π = (2 × π × 2²) + 2 × π × h

56π = 8π + 2πh

56 × 3.14 = (8 × 3.14) + (2 × 3.14 × h)

175.84 = 25.12 + 6.28h

6.28h = 175.84 - 25.12 = 150.72

h = 150.72/6.28

h = 24

Which graph represents the inverse sine function?
hichkok12 [17]
Answer: A.
The inverse sine function is written as sin−1(x) or arcsin(x). Inverse functions swap x- and y-values, so the range of inverse sine is − π/2 to π/2 and the domain is −1 to 1. When evaluating problems, use identities or start from the inside function.

Screen sizes for televisions are measured by the diagonal length from one corner to the opposite corner on the other side. After
JulsSmile [24]

Answer:

<h2>18/√3ft</h2>

Step-by-step explanation:

This is a ratio problem

Step one:

Given the ratio of length:width is <em> "3 space colon space square root of 3"</em>

mathematically it is expressed as

length:width 3:√3 or 3/√3

Step two:

3:√3 or 3/√3

if the built TV has a width of 6ft let the length be x

3/√3=x/6

cross multiply we have

x√3=3*6

x√3=18

x=18/√3ft

therefore the length will be 18/√3ft

Answer: 5

explanation:

4m-2=6
———
3

multiply 3 on both sides to cancel the 3 out

4m-2=18

add 2 from both sides to cancel the 2 out

4m=20

divide both sides by 4 to cancel out the 4
