Sagot :

2. Circumference is around 43.96, area is around 153.94

3. Circumference is around 94.25 and the area is around 706.86

Answer:

area of a circle formula:

radius squared x pi(3.14 or 22/7 most likely whatever they tell you to use in pi)

Circumference formula:

2 x pi(3.14 or 22/7 most likely whatever they tell you to use in pi) x r(radius, if they dont give you the radius but just your diameter for either circumference of area just do half of the diameter shown)

Step-by-step explanation:

First problem:

In this case,

7 is your radius!

7 x 2 x 3.14 (circumference) = 43.96

now area: 7^2 = 49

49 x 3.14 = 153.86

Now time for the other problem:

half of 30 is 15!

15 x 3.14 x 2 (circumference) = 94.2

Area of the circle:

15^2 = 225

225 x 3.14 = 706.5
