Step-by-step explanation:
Given diameter (d) = 28 inches
π = 3.14
Radius (r) = 28/2= 14 inches
Now
Area of the circle
= πr²
= 3.14 * 14²
= 615.44 inch ²

Answer:
160cm^2
Step-by-step explanation:
So the surface area is basicly the sum of all the areas of the rectangles in this prism.
So the formula can be written as
.
The w stands for width, the h stands for height, and the l stands for length.
5cm is the width, 10 cm is the length, and 2 cm is the height.
So inserting all those values for the variabls the formula now looks like this.
.
So 5*10 is <u><em>50</em></u>
2*10 is <u><em>20</em></u>
2*5 is <em><u>10</u></em>
So adding all that up we get 80.
Then multiplyong that by 2 we get 160cm^2.
It already is done i think
