Question

Find the area of this semi-circle with radius,
r
= 32cm.
Give your answer rounded to 1 DP.

Answer 1

Answer:

1608.5$cm^{2}$

Step-by-step explanation:

The area of a circle is π$r^{2}$.

So, it's π * $32^{2}$.

$32^{2} = 1024$

1024 * π = 3216.990877 (using π as 3.141592654)

Divided by 2 (because it's a semicircle), it's 1608.495439.

Rounded to 1 DP, it's 1608.5 $cm^{2}$.
