What do you want to find?
To determine the rounded value to the nearest whole number, we need to find the area of the triangle and the area of the circle.
First, let's calculate the area of the triangle using the formula:
Area = (base * height) / 2
In this case, the base is 11 and the height is 11. Plugging these values into the formula, we get:
Area = (11 * 11) / 2
= 121 / 2
= 60.5
So, the area of the triangle is 60.5.
Next, let's calculate the area of the circle using the formula:
Area = π * radius^2
The given radius is 3.14. Plugging this value into the formula, we get:
Area = π * (3.14)^2
= π * 9.8596
≈ 30.96 (rounded to two decimal places)
So, the area of the circle is approximately 30.96.
Now, to find the rounded value to the nearest whole number, we need to determine whether the decimal part is closer to 0 or 1. In this case, 0.96 is closer to 1.
Therefore, when we round the area of the circle to the nearest whole number, it becomes 31.
So, the rounded value of the area of the circle to the nearest whole number is 31.
