Answer:
Altitude of cylinder = 10 cm
Step-by-step explanation:
Given:
lateral surface area of cylinder = 90 cm²
Circumference of base = 9 cm
Find:
Altitude of cylinder
Computation:
Circumference of base = Circumference of cylinder
So,
2πr = 9
lateral surface area of cylinder = 2πrh
2πrh = 90
We know that; 2πr = 9
So,
9(h) = 90
h = 90 / 9
Altitude of cylinder = 10 cm
Answer:
should be 3
Step-by-step explanation:
The answer is 2 to the power of 6
Answer:
11.25
Step-by-step explanation:
7500 times 0.03 times 5 = 1125
1125 divided 100 = 11.25
simple interest formula = Amount times Rate times Time
Divide 100
ANSWER
No real roots.
The roots are complex or imaginary.
EXPLANATION
The quadratic equation
has discriminant,
If the discriminant is less than zero , then the quadratic equation has no real roots.
The given discriminant is -9.
Since -9 is less than zero, it means the quadratic equation has complex or imaginary roots.
