Answer: 201.06 in²
Step-by-step explanation:
Use the equation πr² to find out the area of a circle.
Since the diameter is 16 the radius is half of that, 8.
π(8)²
Work out that equation and you're done!
This is the leineae making it a because it’s cubic
2x^2-7x-4=0
2x^2-8x+x-4=0
2x(x-4)+1(x-4)=0
(2x+1)(x-4)=0
x=-1/2, 4
Answer:
10.5.
Step-by-step explanation:
By similar triangles:
IJ / 21 = 8 /(8+8) = 1/2
IJ / 21 = 1/2
IJ = 1/2 * 21
= 10.5.
