Answer:
The surface area is
Step-by-step explanation:
we know that
The surface area of the square pyramid is equal to the area of the square base plus the area of its four lateral triangular faces
so
![SA=b^{2}+4[\frac{1}{2}(b)(l)]](https://tex.z-dn.net/?f=SA%3Db%5E%7B2%7D%2B4%5B%5Cfrac%7B1%7D%7B2%7D%28b%29%28l%29%5D)
where

-----> the slant height
substitute the values
![SA=10^{2}+4[\frac{1}{2}(10)(14)]](https://tex.z-dn.net/?f=SA%3D10%5E%7B2%7D%2B4%5B%5Cfrac%7B1%7D%7B2%7D%2810%29%2814%29%5D)
Answer:
The original price of the basketball was $16.80 hope this helps!
Volume of a cone = (PI * radius^2 * height) / 3
Volume of a cone = (PI * 3^2 * 8) / 3
Volume of a cone = (PI * 24)
Cylinder Volume = PI • r² • height
Cylinder Volume = PI * 3^3 * 12
Cylinder Volume = PI * 108
TOTAL Volume = PI * 132
The exact value of sin(7π12) sin ( 7 π 12 ) is √2+√64 2 + 6 4 .
