Step-by-step explanation:
To verify cos²A + sin²A = 1 with A = 90° , then
cos²90° + sin²90°
= (0)² + (1)²
= 0 + 1
= 1
I’m not sure I’m just guessing but maybe 7x minus 35
Let's find area of the base.: 5x4.3=21.5, 21.5/2=10.75
Area of the Faces : 5x3=15/2=7.5x4=30
Let's add 10.75 +30=40.75
I believe C. Sorry if I’m wrong!
The standard equation for the circle centre can be written by using this formula: (x-h)² + (y -k)² = r²
So, the equation in this case is: (x+6)² + (y-7)² = 81
