Answer: 147 cm²
Step-by-step explanation:
    Since it says to use 3 for pi, and the radius is given to us (7 cm), we will plug in and solve for the area.
A = πr²
A = (3)(7)²
A = 147 cm²
 
        
                    
             
        
        
        
Answer:
D
Step-by-step explanation:
First, find the slope of BC :
⇒ m (BC) = -1 - 5 / -3 - 5 
⇒ m (BC) = -6/-8
⇒ m (BC) = <u>3/4</u>
Now, since AD is the altitude of BC, we can say the altitude is perpendicular to BC.
Hence, the slope of a perpendicular line is equal to the negative reciprocal of the original line.
⇒ m (AD) = - (1/m(BC))
⇒ m (AD) = - (1/(3/4))
⇒ m (AD) = -4/3
