Answer:

C =25.12 cm

Step-by-step explanation:

Circumference of a circle is given by

C = pi d

We know that d = 2r  (twice the radius)

C = pi *2r

Substituting in

C = pi*2*4

C = pi*8

Using 3.14 for pi

C = (3.14)*8

C =25.12 cm

rosijanka [135]

Answer:

Step-by-step explanation:

It is given that the distance of the nearest exit door is no more than the 200 feet. so this can be represented using an inequality.

since it is no more than 200 means the maximum it can be is 200 feet .

Now we are representing the distance using the variable d and we have established that the maximum value of d can be 200 so it can represented

by this inequality

d\leq 200

Explain why this statement is true:<br> 7a +4 – 2a = 7a + (-20)+4
MAVERICK [17]

Answer:

This equation has one solution so given statement is true.

Step-by-step explanation:

7a +4 – 2a = 7a + (-20)+4

5a + 4 = 7a - 16

5a - 7a = -16 - 4

- 2a = - 20

a = 10

This equation has one solution so given statement is true.
