A circle has a diameter of 20cm.
20cm
Work out the area of the circle.
Use = 3.14

100 cm² or 314.16 cm²

Step-by-step explanation:

First, you should find the radius of the circle, which is half the diameter.

r = 10 cm

The area of the circle = r²

So you just need to plug in and multiply everything.

A = 10²

= 100 cm²

Usually, you can leave it in terms of pi, but otherwise

= 314.16 cm²

2 and 1.

step-by-step explanation:

plug in each answer. 0 doesn't work, 1 does. so does 2. 4 doesn't:

0 = 1 is not true.

2 = 2 is true.

4 = 4 is true.

8 = 16 is not true.

hope this !

correct answer is option b.

step-by-step explanation:

the true statement about geometric figure is option b that is one line can be drawn through all three points.

if three points are on the same plane, they can be connected by a line.
