Answer:???
Step-by-step explanation:
Since 1 is positive, then D would be your answer.
The corner is 60°, and based on the information given it is D...but if you can measure the angle, it would be B... A and C assume different sizes.
2x^2 - 2x - 12 = 0
a) The GCF is 2x
2(x^2 - x - 6) = 0
What multiplies to negative six and adds to negative 1?
Negative 3 and positive 2.
2(x-3)(x+2) = 0
Solutions:
3, -2
Answer:
r = 2cm
h= 18cm
surface area of cylinder = 2πr ( r + h)
= 2*22/7*2(2+18)
= 125.714cm²
volume of cylinder = πr²h
22/7*(2)²*18
=226.29cm³
