Answer:
8x^2-x-8
Step-by-step explanation:
6x^2 + 3x – 9-(- 2x^2 + 4x – 1 )
6x^2 + 3x – 9+2x^2 - 4x + 1
6x^2+2x^2+ 3x- 4x -9+1
8x^2-x-8
Answer:
34.54
Step-by-step explanation:
According to the scenario, computation of the given data are as follows,
Height (h) = 3.7 km
Base radius (r) = 3 km
We can calculate the volume of mountain by using following formula,
So, volume of cone = (1/3)πh
By putting the value in the formula, we get
= (1/3) π × × 3.7
= 11.1π
= 34.54
Hence, the volume of the mountain is 34.54 .
There are 30.48 centimeters in 12 inches.
Step-by-step explanation:
Given,
1 inch = 2.54 centimeters
For x inches;
x inches = 2.54*x centimeters
x inches = 2.54x centimeters
Number of centimeters in 12 inches
We will put x=12
12 inches = 2.54(12) centimeters
12 inches = 30.48 centimeters
There are 30.48 centimeters in 12 inches.
