Answer:
Use Pythagorean theorem,
Hypotenuse² = base² + altitude²
= 3²+ 6²
= 9 + 36
x² = 45
x = √45
x = 6.71
Step-by-step explanation:
We know, Circumference = 2π * x/2 = <span>π x
In short, Your Answer would be: Option B

Answer:
7z^3+6z^2-27z+22
Step-by-step explanation:
The given question is of subtraction:
So,
(7z^3+42z^2-15z+1)- (36z^2+12z-21)
=7z^3+42z^2-15z+1-36z^2-12z+21
Combining alike terms to simplify
=7z^3+42z^2-36z^2-15z-12z+1+21
=7z^3+6z^2-27z+22
So the answer in simplified form is:
7z^3+6z^2-27z+22 ..
