Looks good to me. Calculation is correct. Although you might want to add to #1 your description; that the width of the rectangle is the circumference of the circle (w = 2πr) and that you add the surfaces together to get the total surface area.
total surface area = area of rectangular part + area of circular parts
SA = 2πrL + 2πr²
Answer:

Step-by-step explanation:
The formula to find the area of a circle is

Let pi be (3.14), the radios as given in the question is (0.9). Therefore;

Answer:
I believe it is 3.75
Step-by-step explanation:
(5^49/5^48)+4^0−(1)^79⋅(−3/−4^9)^0
5+1−(1)^79⋅(−3/−4^9)^0
5+1−(1)^79
5⋅(−3/−4^9)^0
-3 divided by -4 to the power of 9 to the power of 0=0.75
5 times 0.75=3.75
Hope this is correct! xx
