Solution:

We know that:

Diameter = 22 meters
Radius = Diameter/2
Area of circle = πr²

Finding the radius:

Radius = Diameter/2
=> Radius = 22/2
=> Radius = 11 meters

Finding the area of the circle:

Area of circle = πr²
=> Area of circle = (3.14)(11²)
=> Area of circle = 3.14 x 121
=> Area of circle = 379.94 m²

Answer:

379.94 m²

Step-by-step explanation:

Given :-

Diameter = 22 m

To Find :-

Area

Formula Required :-

Area (circle) = πr²

Solving :-

Area = 3.14 x 11 x 11

= 3.14 x 121

= 379.94 m²

Solution :-

379.94 m²

I honestly done know what to do (look at image)

NARA [144]

Answer:

A is x - 4n / 3, B is 6k + 9n, C is 11k + 16n

Step-by-step explanation:

Pretty simple, you are adding the algebra grids, or substituting variables and making out an equation.

Solving for B: 4k + 6n + 2k + 3n = 6k + 9n

Solving for A: (2k + 3n) + x = 5k + 7n = x - 4n / 3

Solving for C: 6k + 9n + 5k + 7n = 11k + 16n

In circle P, chord AB is 3 inches from the center and chord CD is 5 inches from the center. Chord CD is ____ than chord AB.

Leno4ka [110]

The chord that goes through the center of a circle, the diameter, is the longest chord in a circle. Any other chord will be shorter than this. The farther a chord is away from the circle, the shorter it will be. This means that chord CD is shorter than chord AB.

Solve the system using the substitution method 3x-y=4 5x+3y=9

rjkz [21]

First solve the first equation for 'y'
3x - y = 4 subtract 3x from both sides
-y = -3x + 4 divide both sides by -1
y = 3x - 4 Now take this equation and substitute into the second equation:

5x + 3y = 9
5x + 3(3x - 4) = 9
5x + 9x - 12 = 9
14x - 12 = 9
14x = 9 + 12
14x = 21
x = $\frac{21}{14} = \frac{3}{2}$ or 1.5
Now substitute this value for 'x' into either of the first two equations to find 'y'
I'll use the equation
y = 3x - 4
y = 3(1.5) - 4
y = 0.5

So your solution is (1.5, 0.5)
