1. Find the area of the figure.(The figure is a trinagle with a dotted line directly down the middle with the measurements of 4 by 9 ft) A~18 FT2?
2. Find the area of the figure. Use 3.14 for and round your answer to one decimal place(The figure is a cirle with a dot in the midlle then we have a line all the way across measurting 9yd) A~63.6 SQ YD?
Both correct!
1. To find the area of the triangle, we can use the formula: Area = 0.5 * base * height.
Since the base of the triangle is 4 ft and the height is 9 ft, we can substitute these values into the formula:
Area = 0.5 * 4 ft * 9 ft = 18 ft2.
So, the area of the triangle is approximately 18 ft2.
2. To find the area of a circle, we can use the formula: Area = π * radius^2.
Given that the diameter of the circle is 9 yd, we can calculate the radius by dividing the diameter by 2:
Radius = 9 yd / 2 = 4.5 yd.
Now we can substitute the radius value into the area formula:
Area = 3.14 * (4.5 yd)^2 ≈ 3.14 * 20.25 yd^2 ≈ 63.6 sq yd.
Therefore, the area of the circle is approximately 63.6 square yards.
1. To find the area of the triangle, we need to use the formula for finding the area of a triangle, which is:
Area = (base * height) / 2
In this case, the base of the triangle is the line down the middle, which has a length of 4 ft. The height of the triangle is the distance from the line down the middle to the top of the triangle, which has a length of 9 ft.
Let's plug these values into the formula:
Area = (4 ft * 9 ft) / 2
Area = 36 ft² / 2
Area = 18 ft²
Therefore, the area of the triangle is approximately 18 ft².
2. To find the area of the circle, we need to use the formula for finding the area of a circle, which is:
Area = π * (radius)²
In this case, the line across the circle represents the diameter of the circle, which is equal to 9 yards. To find the radius, we need to divide the diameter by 2:
Radius = 9 yd / 2
Radius = 4.5 yd
Next, let's plug this value into the formula:
Area = 3.14 * (4.5 yd)²
Area = 3.14 * 20.25 yd²
Area ≈ 63.6 yd² (rounded to one decimal place)
Therefore, the area of the circle is approximately 63.6 square yards.
