154 square inches.
In a circle, the circumference and diameter vary directly. Which of the following equations would allow you to find the diameter of a circle with a circumference of 154 if you know that in a second circle the diameter is 14 when the circumference is 44?
Radius of circle: 44/(2*pi) = 7 cm rounded Area of circle: pi*7^2 = 154 square cm rounded
12.4
diameter = 43.98226/pi = 13.99998817 radius = 13.99998817/2 = 6.999994087 area = pi*6.9999940872 = 153.93778 or about 154 square units
If the circumference of a circle is 44 inches, the area is: 154 square inches.
154 square inches.
pi R2 = 154R2 = 154/piR = sqrt(154/pi)D = 2 sqrt(154/pi)C = pi D = 2 pi sqrt(154/pi) = 2 sqrt(154 pi) = 43.991 = 44 inches (rounded)
Area = pi*72 = 153.93804 or about 154 square units
In a circle, the circumference and diameter vary directly. Which of the following equations would allow you to find the diameter of a circle with a circumference of 154 if you know that in a second circle the diameter is 14 when the circumference is 44?
Radius of the circle will be 7 inches and its area is pi*7^2 = 154 square inches rounded to a whole number
Radius of circle: 44/2*pi = 7 rounded Area of circle: pi*7 squared = 154 square cm rounded
Radius of circle: 44/(2*pi) = 7 cm rounded Area of circle: pi*7^2 = 154 square cm rounded
Well, darling, to find the diameter of a circle when you know the circumference, you simply divide the circumference by π (that's pi, sweetie). So, if your circumference is 154, just divide that by π (approximately 3.14159) to get the diameter. That's the tea, honey!
I assume that a 14 inch circle is a circle 14 ionches in diameter. Use the formula Area = Pi x radius of the circle X radius of the circle The radius is half the diameter. Pi is 3.14159 (appx) So the area = 3.14159 X 7 X 7 = 153.937 square inches. Or approximately 154 square inches
