Find the diameter and the circumference of the circle below r=8cm

Mathematics
1 answer:
vfiekz [6]2 years ago

Answer:

diameter = 16cm, circumference ≈ 50.27

Step-by-step explanation:

The radius is 8 centimeters, so the diameter should be twice of that because the radius is the distance from the middle of the circle to the edge while the diameter is from edge to edge passing through the middle of the circle. Therefore,

8 · 2 = 16cm

The equation for the circumference of a circle is 2πr. In this case, because nothing else is specified about π, we use 3.14. So,

2 · 3.14 · 8 ≈ 50.27

Hope this helped! Have a great day. ^^

Andreas93 [3]

Answer:

$70

Step-by-step explanation:

Middletown Equation:

1c +50 = T

Sweet Shoppe Equation:

2c + 30 = T

Set equations equal to one another and solve for first for cupcakes then for cost.

1c + 50 = 2c + 30

c+ 20 = 2c

20 = c (twenty cupcakes would be ordered)

Now insert into either equation ( or both to check)

1(20) + 50 = 70

2(20)+ 30 = 70

Total cost would be $70

HOPE THIS HELPS!!!

disa [49]

Answer:

μv =50 cm^{3}

σv= 3 cm^{3}

Step-by-step explanation:

Volume is found by multiplying the area and height. Since we're given both area and height of 10 and 5 cm respectively then

μv =A.h= 10*5= 50 cm^{3}

The standard deviation of the volume will be

σv= 0.3*10= 3 cm^{3}
