Step-by-step explanation:
Here Given
Diameter (d) = 8
radius (r) = d/2 = 8/2 = 4
Now
Area
= 
= 
= 16
Hope it helped :)
Area of a circle: A = πr²
Find the radius by dividing the diameter by 2.
8 / 2 = 4
Find the area using the given values (r = 4).
A = π(4)²
A = 16π (in terms of π)
A = 50.24 (as a decimal)
Therefore, you can put the answer as 16π or 50.24
Best of Luck!

Answer:
b squared minus 4ac describes the discriminant which means the amount of solutions that the equation will have.
This is how the sketch should look on your graph!
X + y = 22
x = 3y + 2
3y + 2 + y = 22
4y + 2 = 22
4y = 22 - 2
4y = 20
y = 20/4
y = 5
x = 3y + 2 = 3(5) + 2 = 15 + 2 = 17
ur numbers are 5 and 17
Question a:
f(6) = (6)² + 2(6) + 8
f(6) = 36 + 12 + 8
f(6) = 56
Question b:
f(x+4) = (x+4)² + 2(x+4) + 8
f(x+4) = x² + 8x + 16 + 2x + 8 + 8
f(x+4) = x² + 10x + 32
Question c:
f(-x) = (-x)² + 2(-x) + 8
f(-x) = x - 2x + 8
