Answer:

Area : 153.86cm

Circumference: 43.96cm

Step-by-step explanation:

To Find:

Area __ cm

Circumference__ cm

Given:

Since, it given that the Diameter is 14 cm

Diameter which is any straight line segment that passes through the center of the circle.

Radius which is half of diameter

Note:

A = πr ² {Area Formula}

C = rd {Circumference Formula}

pi also known as π = 3.14 {approximately }

"r " means Radius

"d " means diameter

c = circumference

a = area

Solve:

A = πr ²

Since radius is half of the diameter then...

14/2 = 7

Radius = 7

A = 3.14(7)² { (7)² means 7 × 7 Not 7 × 2 }

A = 3.14(49) { 7 × 7 = 49}

A = 153.86

C = rd

C = 3.14(14)

C = 43.96

Area : 153.86cm

Circumference: 43.96cm

Solve the equation 2(x-4)=-22

Tcecarenko [31]

Hello Lexi!

Answer: ⇒⇒⇒⇒⇒⇒ $x=-7$

__________________________________________________________

Step-by-step explanation:

First you had to divide by 2 from both sides of equation.

$\frac{2(x-4)}{2}=\frac{-22}{2}$

Simplify.

$\frac{2(x-4)}{2}=x-4$

$\frac{2(x-4)}{2}$

Divide by the numbers.

$\frac{2}{2}=1$

$=x-4$

$\frac{-22}{2}=-11$

Apply the fraction rule.

$\frac{-22}{2}$

$=-\frac{22}{2}$

Then you divide by the number.

$\frac{22}{2}=11$

$=-11$

$x-4=-11$

Add by 4 from both sides of equation.

$x-4+4=-11+4$

Simplify it should be the correct answer.

$x=-7$

Median: 16

Mode: 10

Step-by-step explanation:

8, 10, 10, 11, 16, 17, 19, 21, 41

Median: (the middle number in the number list/data set) 16

Mode: 10

Mean: 8 + 10 + 10 + 11 + 16 + 17 + 19 + 21 + 41 = 153/9 = 17
