Answer:
g(2y) = 8y^2 -3
Step-by-step explanation:
g(x)=2 x^2 -3
Let x=2y
g(2y) = 2 (2y)^2 -3
= 2 (4y^2) -3
= 8y^2 -3
The area of circle can be found using the formula πr² and since we know that semi circle is half the circle so its formula will be 1/2πr².
First we will find the radius.
20/2 = 10
Radius is 10.
A = 1/2(3.14)(10)²
A = 157
Hope this helps :)
