Question

the diameter of a circle is 4 cm. find it's area in terms of pi?!​

Answer 1

Step-by-step explanation:

Radius of the circle = Diameter / 2 = 2cm.

Area = pi * (Radius)² = 4pi cm².

Answer 2

Answer:

4$\pi$

Step-by-step explanation:

Radius is always half of the diameter.

So, 4/2=2

Now that we know the radius, we find the are.

The equation for area is $\pi r^2$. When you insert everything, you get....

$\pi$$*$$2^{2}$  

When you put it all together, we get... 4$\pi$

Hope this helped :)
