Answer: 423.11 m^2
Step by step explanation:
Area of a circle formula pi*r^2
First solve the area of the big circle
3.14*21^2=1384.74 m^2
Now find the are of the smaller circle
r=21-3.5=17.5
3.14*(17.5)^2=961.63 m^2
Now we can minus the small area off the big area to get the shaded area.
1384.74-961.63=423.11 m^2
So the area of the shaded region is 423.11 m^2
Answer:
44,55,000 cubic meters of treasure could fit the pyramid.
Step-by-step explanation:
We are given the following in the question:
Base measure = 450 meters
Height = 66 meters
The volume of the pyramid is given by:

where A is the ares of the base and H is the height of the pyramid.
Putting values, we get,

Thus, 4455000 cubic meters of treasure could fit the pyramid.
Difference of two squares is of the form (a + b)(a - b) or vice-versa. Here, a = -5x and b = 3.
(-5x - 3)(-5x + 3)
