Answer:

6cm

Step-by-step explanation:

to find the diameter of a circle whose  circumference is = 18 .84

the formula for finding the circumference of a crcle = πd

18.84 = πd

note π = 22/7 or 3.14

so,

18. 84 = 3.14 × d

divide both sides by 3.14

18.84/3.14 = 3.14d/3.14

6cm = d

therefore the diameter of the circle whose circumference is 18.84 is equal to 6cm

Damm [24]

Answer:

\boxed{D = 15.8\ units}

Step-by-step explanation:

The coordinates are (0,9) and (-8,-4)

Distance Formula = \sqrt{(x2-x1)^2+(y2-y1)^2}

D = \sqrt{(-8-0)^2+(-4-9)^2}

D = \sqrt{(-8)^2+(-13)^2}

D = \sqrt{81+169}

D = \sqrt{250}

D = 15.8 units

cricket20 [7]

Answer:

Width = 44 yards

Length = 171 yards

Step-by-step explanation:

given data

length of the field = 5 yards

Perimeter of the rectangular field = 430 yards.

solution

we consider here length of the field = L

and width of the field = W

as we know length of the field 5yards less than quadruple the width

so here

L = 4W - 5       .....................................1

and  

Perimeter (P) will be here

P = 2(L + W)      ............................................2

put here equation 1 value

430 = 2(4W - 5 + W)  

solve it we get

W = 44

so here put value in eq 1 we het

L = 4W - 5          

L = 4(44) - 5

L = 171

so, length of the field is 171 yards
