Answer:
Option "C" is the correct answer to the following question.
The lateral surface area of cube = 144 Ft²
Step-by-step explanation:
Given:
Side of cube = 6 Ft
Find:
The lateral surface area of cube =?
Computation:
⇒ The lateral surface area of cube = 4a²
⇒ The lateral surface area of cube = 4 × 6 × 6
⇒ The lateral surface area of cube = 144 Ft²
All sides of the cubes are equal. The lateral surface area of cube is also known as the curved surface area of the cube.
You need to find the perimeter so your units would be feet.
LETTER B
( - 8 + b )( - 4 - 3 ) = 0;
( - 8 + b )( - 7 ) = 0 ;
-8 + b = 0;
b = 8.
Answer:
1/2
Step-by-step explanation:
if you look at a unit circle, sin(\pi/6) is so cos of (\pi/6/2) would be \pi/3, and cos of (\pi/3) is 1/2
