Question

Group of questions if able to provide the steps for each

Answer 1

Answer:A

Step-by-step explanation:

4th image the answer is A) 15.7 / pi = d

the formula:pi d = circumferance

we know that the circumferance is 15.7 cm so you can do the opposite.

pi = 3.142

If we do 15.7 / 3.142 we get 5 rounded up and we can check for any mistakes by doing 5 pi and its correct because we get 15.71 cm which is the same as 15.7 cm

answer is A)

Answer 2

Answer to 3rd image = b: the area of the circle is approximately 3 times greater than the circumferance

Step-by-step explanation:

Circumferance =

`\pi d`

Using this we can figure out that the circumferance is 37.704 cm or if we round it then it will be 38 cm.

Area of a circle =

`\pi r^(2)`

Using this we can find that the area would be 113.112 cm² or if we round it, it becomes 114 cm².

Now let's go through the statements:

A) We know that there's no way that area is 8 times larger than circumferance because it would be 304 cm

C) The circumferance can't be an eight of the area as its approximately 4 times smaller.

D) The circumferance can't be 4 times greater as its 4 times smaller and its less than the area

We are left with B) which is the answer because 4 times the curcumferance would be 152 cm which is close enought to the area

so B) is the answer

For 4th image the answer is A) 15.7 / pi = d

Explanation:

We know that to find circumferance we use the formula:

pi d = circumferance

so we know that the circumferance is 15.7 cm so we are going to do the opposite.

pi = 3.142

If we do 15.7 / 3.142 we get 5 rounded up and we can check for any mistakes by doing 5 pi and its correct because we get 15.71 cm which is the same as 15.7 cm

so the answer is A)
