Answer:
Step-by-step explanation:
To simplify this fractional exponent we apply exponential property
As per this property , we multiply the exponent inside the fraction
Multiply the exponent 11 inside the fraction
Multiply the exponent 11 with 7 and then 4
When you multiply an exponent directly into another exponent, you multiply the exponents
(for a fraction, you multiply the exponent to both the numerator and denominator)
For example:
Your answer is A
300Pi cubic feet
1,500Pi cubic feet
2,250Pi cubic feet
6,000Pi cubic feet
1500 cubic feet water is needed to fill the tank. Option B.
Step-by-step explanation:
Given,
The diameter of the cylindrical water tank is 20 ft.
So, the radius (r) = 10 ft
Height (h) = 15 ft
To find the water to be filled in the tank we need to find out the volume.
Formula
volume of cylinder (V) = πr²h
Now,
Putting the values of r and h in the given formula we get,
V = π×10²×15 = 1500π cubic feet
Hence,
1500 cubic feet water is needed to fill the tank.
Answer:
b
Step-by-step explanation:
Answer:
first X=8.94
second X=34
Step-by-step explanation:
5) x^2=4^2+8^2
x^2=16+64=80
x=8.94
6)x^2= 31^2+14^2
x^2=961+196
x^2=1157
x=34
