√224/√7
= √(224/7)
= √32
= 4√2
Therefore, √224/√7 = 4√2
To find the area of a circle, we use the formula A = πr^2, where r is the radius of the circle.
Since the diameter of the circle is 11 cm, the radius (r) is half of the diameter, so r = 11/2 = 5.5 cm.
Now, we can calculate the area by substituting the radius into the formula:
A = π * (5.5)^2
A = π * 30.25
A ≈ 94.9875
Rounded to the nearest tenth, the area of the circle is 95.0 square cm.
To find the area of a circle, we use the formula A = πr^2, where r is the radius of the circle.
Given that the diameter of the circle is 10 m, we first need to find the radius (r) by dividing the diameter by 2:
r = 10 / 2 = 5 m
Now, we can calculate the area by substituting the radius into the formula:
A = π * (5)^2
A = π * 25
A ≈ 78.54
Rounded to the nearest 10th, the area of the circle is 78.5 square meters.
The diameter of a circle is 11 cm find its area to the nearest 10th
The radius of a circle is 8 cm find its area to the nearest whole number
Given that the radius of the circle is 8 cm, we can calculate the area using the formula A = πr^2:
A = π * (8)^2
A = π * 64
A ≈ 200.96
Rounded to the nearest whole number, the area of the circle is 201 square cm.
The diameter of a circle is 10 m find its area to the nearest 10th
The diameter of a circle is 14 m find its area to the nearest whole number
Given that the diameter of the circle is 14 m, the radius (r) is half of the diameter, so r = 14/2 = 7 m.
Now, we can calculate the area using the formula A = πr^2:
A = π * (7)^2
A = π * 49
A ≈ 153.94
Rounded to the nearest whole number, the area of the circle is 154 square meters.
