Answer 3

they have given you the formula so for part a just replace r with 3 and s with 5

Answer 4

ok

Answer 5

3.14+(3)(5)+(3^2)?

Answer 6

Here, we basically put the values into the equation.

3.14(rs + r^2)
r = 3 and s = 5

Answer 7

Now, can you replace the values into the expression?

Answer 8

ok

Answer 9

Or do you need some help?

3.14(rs + r^2)
3.14(3*5 + 3^2)

Answer 10

Simplify that ^

Answer 11

Part A: is asking for an expression with the values put in.

3.14(3*5 + 3^2)

^ That would be our answer, since we plugged the values inside,

Answer 12

Now, for Part B

Answer 13

3.14(3*5 + 3^2)
3.14(15 + 9)
3.14(24)
75.36

So, our surface area = 75. 36 units squared

Answer 14
