Answer:
r≈4.51yd
Step-by-step explanation:
The surface area of a sphere is given by the formula SA = 4r2, where r is the radius of the sphere. If the surface area of a sphere is 256 square yards, then the radius of the sphere is 4.51yd.
Formula: A=4πr^2
Answer:
10226 ft
Step-by-step explanation:
Let x be the sea level, A horizontal imaginary line on the sea's surface.
-Given that Salton is -226 ft below this line and the mountain is 10000ft above sea. The difference between this elevetions is calculated as;
![\bigtriangleup =Mountain \ Peak-Sea \ bottom\\\\=10000-(-226)\\\\=10000+226\\\\=10226](https://tex.z-dn.net/?f=%5Cbigtriangleup%20%3DMountain%20%5C%20Peak-Sea%20%5C%20bottom%5C%5C%5C%5C%3D10000-%28-226%29%5C%5C%5C%5C%3D10000%2B226%5C%5C%5C%5C%3D10226)
Hence, the difference between the two elevations is 10226 ft

What is octagonal in shape?
- In geometry, an octagon is a polygon that has 8 sides and 8 angles.
- All the sides are joined end to end to form the shape of the octagon.
- The sum of the interior angles of an octagon is equal to 180 degrees.
Solving for an area of a regular octagon, we can make use of the formula shown below:
Area = 1/2 × apothem × perimeter
In this problem, the following values were given such as:
Apothem = 10 inches
Perimeter = 66.3 inches
Put the values in the formula
Area = 1/2 × 10 × 66.3
Area = 331.5 inches²
