Volume of a pyramid=1/3*base area*height
volume=1/3*(755.9*755.9)*480.6
volume=1/3*571384.81*480.6
volume=91535846.56ft cube
Answer:
Around 55.9
Step-by-step explanation:
The first step is to find the area of segment of the circle. Since the segment is a 90 degree angle and a total circle is 360, it is a quarter of the area of a circle. Therefore, you can find its area with the formula
. Now, you can find the area of the triangle inside. Since all of the radii in a circle are the same length, the triangle has two sides of length 14. Using the triangle area formula, you get an area of 14*14/2=98 square centimeters.
square centimeters. Hope this helps!
