Answer: the diameter of the circle is 226 cm

Step-by-step explanation:

The formula for determining the length of an arc is expressed as

Length of arc = θ/360 × 2πr

Where

θ represents the central angle.

r represents the radius of the circle.

π is a constant whose value is 3.14

From the information given,

Length of arc = 88π

θ = 140 degrees

Therefore,

88π = 140/360 × 2 × π × r

88π = 140/360 × 2 × π × r

Dividing both sides of the equation by π, it becomes

88 = 140/360 × 2r

88 × 360 = 140 × 2r = 280r

280r = 31680

r = 31680/280

r = 113 cm

Diameter = radius × 2

Diameter = 113 × 2 = 226 cm

What is the solutions of the equation 2 (x+2) ^2-4=28
JulsSmile [24]

Answer:

x = 2            x = -6

Step-by-step explanation:

2 (x+2) ^2-4=28

Add 4 to each side

2 (x+2) ^2-4+4=28+4

2 (x+2) ^2= 32

Divide by 2

2/2 (x+2) ^2=32/2

(x+2)^2 = 16

Take the square root of each side

sqrt((x+2)^2) =±sqrt( 16)

x+2 = ±4

Subtract 2 from each side

x+2-2 = -2±4

x = -2±4

x = -2+4      and x = -2-4

x = 2            x = -6

Brooke had 70 chairs but he had less than20 rows how many chair he can put on each row
RideAnS [48]
Put in a equality

20 > (70/x)

then you solve 

20x > 70

x>70/20

x> 3.5    you can not put part of a chair in a row so you round up

****You can put  4 or more chairs in a row****
