Answer:
-9
Step-by-step explanation:
We are given the expression m–[(m–n)÷(−2)](−5). Substituting -4 for m and -6 for n, we get:
-4–[(-4 + 6)÷(−2)](−5)
We must do the work that appears inside parentheses first:
-4–[( 2 )÷(−2)](−5)
Next we must do the work that appears inside square brackets:
-4–[ -1 ](−5)
Multiplication comes next. The above expression becomes:
-4 - [ 5 ]
which in turn comes out to -9
Calculate the circumference and then add the 1 cm overlap:
C = pi*(6.6 cm) + 1 cm = 21.7 cm.
Next, mult this C by the height, 8.8 cm: Total area is 21.7 cm times 8.8 cm,
or 191.3 cm^3 (answer)
The answer to Number 3 is B
