Question

Find the area of this semi circle ...

Answer 1

Here's the equation for the area of a semicircle: A = (πr²)/2

Based on this, let's solve for this area in terms of π (pi):

A = π(10²)/2 = 100π/2 = 50π

The area of the semicircle, I believe, is 50π. Hope this helps, let me know if I messed up!

Answer 2

Answer: A=157

Step-by-step explanation: The area of a semi-circle can be found using the radius in the formula A=1/2$\pi$r^2. We substitute the radius in the equation  A=1/2*3.14*10^2

First we do the exponents following pemdas.

A=1/2*3.14*10^2

A=1/2*3.14*100

Then we multiply.

A=1/2*3.14*100

A=1.57*100

A=157

The final answer is 157.

Hope this helps!
