Question

a) Find the area of a circle with radius 10 units.

Answer 1

Answer:

100π or 314

Step-by-step explanation:

The formula for the area of a circle is πr²

r being the radius

If our radius is 10, then it will be π(10)^2 or 100π

If we round π to 3.14, then 100π=100(3.14)=314

Answer 2

Answer: A = 100$\pi$ = 314.159

Step-by-step explanation:

-To find the area of a circle, you need the formula:

$A = \pi r^2$

-Next, you put the radius on that equation:

$A=\pi 10^2$

-Then, you solve it:

$A= \pi$ × $10^2$

$A= \pi$ × $100$

$100\pi =314.159$

So, the area of a circle should be = 314.159
