Hey there!
The answer is
We will start by forming an equation to solve this.
So we are starting with a number, , then doubling it and adding , which gives us 25.
So:
Now we solve this equation:
Have a super awesome day!
Area of a semicircle =
r² / 2
r= 5/2 = 2.5
So: A= 3.14 x 2.5² / 2 A = 9.8125 so rounding to the nearest hundredth is A=9.81
Do 4x5 then add 00 at the end, 4x5 = 20 then add the two 0s so it would be 2000, so it is 2000
