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 .
Answer:
B) identity property of addition.
Step-by-step explanation:
Given:
The statement given is:
Here, we observe that 10 is added to a giving the number 10 itself as the answer. So, we know of a property which says that when 0 is added to a number, the result is the number itself. This property is called identity property of addition.
So, the value of must be 0 because on adding
to 10, we are getting the number 10 only. So, the above statement is an example of identity property of addition.
