D. The volume of square based pyramid is 1280 
Step-by-step explanation:
Given:- A square base pyramid of,
Base edge (b) =16 inches.
Height (h)= 15 inches.
To find:- Volume of the square bases pyramid=?
Solution:-
As the given pyramid is a square based pyramid, therefore the formula to find the volume for square based pyramid is,
Volume of square based pyramid = 
where, b is the base edge and h is the height of the pyramid.
Volume of square based pyramid = 
Volume of square based pyramid = 
Volume of square based pyramid = 
Volume of square based pyramid = 1280 
Therefore the volume of square based pyramid is 1280 
Answer:
The length of the arc is 10 pi
Step-by-step explanation:
Mathematically, the length of an arc is calculated as;
theta/360 * 2 * pi * r
theta represents the central angle subtended by the arc which is a right angle according to the question (a right angle is 90 degrees)
r is the circle radius which is 20 inches
so we have the length of the arc as;
90/360 * 2 * pi * 20 = 40 pi/4 = 10 pi
