Answer:
for perimeter you add all sides. so Lenth x2 + width x2 is 24+30 which would equal 54
for area it's Lenth times width so 12 times 15 equals 156
Answer:
![v = \pi \times {r}^{2} \times h](https://tex.z-dn.net/?f=v%20%3D%20%5Cpi%20%5Ctimes%20%7Br%7D%5E%7B2%7D%20%20%5Ctimes%20h)
Step-by-step explanation:
height=11km
diameter=10km
radius=diameter÷2
=10÷2
=5km
now,
volume=
![\pi \times {r}^{2} \times h \\ \frac{22}{7} \times {5}^{2} \times 11 \\ \frac{6050}{7} \\ 864.3 \: {km}^{3}](https://tex.z-dn.net/?f=%5Cpi%20%5Ctimes%20%20%7Br%7D%5E%7B2%7D%20%20%5Ctimes%20h%20%20%5C%5C%20%20%5Cfrac%7B22%7D%7B7%7D%20%20%5Ctimes%20%20%7B5%7D%5E%7B2%7D%20%20%5Ctimes%2011%20%20%5C%5C%20%5Cfrac%7B6050%7D%7B7%7D%20%20%5C%5C%20864.3%20%5C%3A%20%20%7Bkm%7D%5E%7B3%7D%20)

Step-by-step explanation:
Answer:
The equation to calculate the average rate of change is: y/x
Step-by-step explanation:
y = f(x2) - f(x1)
x = x2 - x1
x1: 1 (The smaller x value. It can be any number)
x2: 2 (The larger x value. It also can be any number)
f(x1): The value when you plug x1 into the function.
f(x2): The value when you plug x2 into the function.
If we know this, the variables for this problem are assuming the function is 10(5.5)^x:
x2: 2
x1: 1
f(x2): 10(5.5)^(2) = 302.5
f(x1): 10(5.5)^(1) = 55
This means:
y = 302.5 - 55 = 247.5
x = 2 - 1 = 1
Remember: the equation for avg rate of change is y/x
So, our average rate of change for the function on the interval [1,2] is 247.5 (y/x = 247.5/1)
