Answer:
18
Step-by-step explanation:
The height of the cone is 8, and the diameter is 3. This means that the radius is 3/2, or 1.5. We can plug everything into the formula (using 3 for pi):

We can cancel out the 3 from the numerator and the denominator, so we are left with 1.5^2 times 8. 1.5 squared is equal to 2.25, and 2.25 times 8 is equal to 18.

The measure of angle (m ∠A) is 136°
<h3>Vertical angles theorem</h3>
From the question, we are to find the measure of angle A
From the given information, we have that 
∠A and ∠B are vertical angles
Thus 
∠A = ∠B 
and 
Also, from the given information,
m ∠A=(2x+26)° 
and 
m ∠B= (3x−29)° 
∴ (2x+26)° = (3x−29)°
Now, solve for x 
2x + 26 = 3x - 29 
26 + 29 = 3x - 2x 
55 = x 
∴ x = 55
But measure of angle A is given by 
m ∠A=(2x+26)°
Put the value of x into the equation, 
m ∠A=(2(55)+26)°
m ∠A=(110+26)°
m ∠A = 136°
Hence, the measure of angle (m ∠A) is 136°

Answer:
C
Step-by-step explanation:
The quotient is 18
 
        
             
        
        
        
6r - 3t = 6     /*8
6r + 8t = - 16  /*3
48r - 24t = 48
48r + 24t = - 48
---------------------- + 
96r = 0
r = 0
t = ( -16 + 6r)/8 = - 16/8 = - 2
