Answer:
v= 1150.35 or v=143.79
Step-by-step explanation
if 6.5 is the radius then v= 1150.35 or if 3.25 is the radius then v=143.79
x2+11x+28
Step-by-step explanation:
Thus, (x+7)(x+4) multiplies out to x2+4x+7x+28, which can be simplified to
9 × 7 + (8 - 5) = 66
9 × 7 + 8 - 5 = 66
Applying the order of operations (PEMDAS);
The parenthesis would go to 9 × 7 + (8 - 5) = 66
The answer is in my photos.
