Jacob used an empty can for a project shown below the pills the label of the king in find the area of the label what is the approximate area of the canned label?

Answers

Answer:

B: 100.53 in²

Step-by-step explanation:

From the image of the can label shown, we can see that;

Height; h = 8 inches

Diameter; d = 4 inches

Thus, radius; r = d/2 = 4/2 = 2 inches

The can is a cylinder and the label covers only the curved surface area. Thus, formula for curved surface area of a cylinder is;

A = 2πrh

Thus;

A = (2π × 2 × 8)

A = 100.53 in²

I need the value of x. 10x + 4 - 2x = 6x + 9 + 7

Answers

Answer:

x = 6

Step-by-step explanation:

Answer:

x=6

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

10x+4−2x=6x+9+7

10x+4+−2x=6x+9+7

(10x+−2x)+(4)=(6x)+(9+7)(Combine Like Terms)

8x+4=6x+16

8x+4=6x+16

Step 2: Subtract 6x from both sides.

8x+4−6x=6x+16−6x

2x+4=16

Step 3: Subtract 4 from both sides.

2x+4−4=16−4

2x=12

Step 4: Divide both sides by 2.

2x=12

i will give u the brainliest i need the answer with the steps .pls abswer soon☺☺

Answers

Answer:

ab = 24

so ac is half, so

ac = 12

and the radius is 13,

draw a line from a to o

and its tall will be 13 because it is the radius and o is the center

now use Pythagoras rule

[tex] {a}^{2} + {b}^{2} = {c}^{2} [/tex]

put numbers

[tex] {12}^{2} + {b}^{2} = {13}^{2} [/tex]

and solve for b

b = 5
