The formula for finding the area of a full circle is πr2, I believe<span>, where "r" represents the </span>radius<span> of the circle. Since you're finding the area of a semi-circle, you'll be looking for half of the area of a circle, which means you have to use the formula for finding the area of a semi-circle and then divide it by two.
I'm not a 100% sure here. But I believe.

Two numbers total 66 and have a difference of 22. Find the two numbers​
olganol [36]
<h3>♫ - - - - - - - - - - - - - - - ~Hello There!~ - - - - - - - - - - - - - - - ♫</h3>

➷ x + y = 66

y - x = 22 (rearrange for y)

y = x - 22 (substitute this into the top equation)

x + (x - 22) = 66

2x - 22 = 66

Add 22 to both sides

2x = 88

x = 44

The two numbers are 44 and 22

➶ Hope This Helps You!

➶ Good Luck (:
