What is the area of a circle that has a diameter of 18 cm?
A circle with a radius of 9 cm has an area of 254.47 square cm
What is the area of a circle when a chord length is 9 cm and its midpoint is 6 cm from the circle's centre?
Using 3.14 as Pi the area of circle is: 0
What is the diameter of a circle with an area of 254 cm?
Circle area = (pi)r2 = 254r2 = 254/pir = √254/pi ≈ 92r = diameter = 2(9) = 18 cm
What is the area of a circle with 120 degrees if the radius is 9 cm?
I assume you want the area of the sector with angle 120o and radius 9 cm: 120o is 120/360 = 1/3 of a full circle. ⇒ area of sector is 1/3 area of full circle ⇒ area_of_sector = 1/3 x π x radius2 = 1/3 x π x (9 cm)2 = 27π cm2 ≈ 84.82 cm2
What is the exact area of a circle with a diameter of 6cm?
The exact area = pi*32 or 9*pi square cm
What is the area of a circle that has a diameter of 18 cm?
A circle with a radius of 9 cm has an area of 254.47 square cm
If a circle as the radius of 9 cm what is its area?
The answer is 254.469005cm squared
The diameter of a circle is 9 cm What is the area of the circle?
pie x 4.5 squared
What is the area of a circle when a chord length is 9 cm and its midpoint is 6 cm from the circle's centre?
Using 3.14 as Pi the area of circle is: 0
What is the diameter of a circle with an area of 254 cm?
Circle area = (pi)r2 = 254r2 = 254/pir = √254/pi ≈ 92r = diameter = 2(9) = 18 cm
What is the area of a circle that has a diameter of 9 cm?
The area of a circle is figured out using the formula Now, the circle we are given has a radius of 9cm. So, the area of the circle would be: Area = 3.14 x (9)2 = 3.14 x 81 = 254.34 cm2 The area of the circle in question is 254.34 cm2
What is the segment area of a minor chord with an arc of 40 degrees within a circle which has a radius of 9 cm showing work?
There must be an isosceles triangle within the circle and so:- Area of sector: 40/360*pi*9*9 = 9*pi square cm Area of triangle: 0.5*9*9*sin(40 degrees) = 26.03289819 square cm Area of segment: 9*pi-26.03289819 = 2.241435692 square cm or 2.241 to 3 d.p.
What is the area of a circle with 120 degrees if the radius is 9 cm?
I assume you want the area of the sector with angle 120o and radius 9 cm: 120o is 120/360 = 1/3 of a full circle. ⇒ area of sector is 1/3 area of full circle ⇒ area_of_sector = 1/3 x π x radius2 = 1/3 x π x (9 cm)2 = 27π cm2 ≈ 84.82 cm2
What is the exact area of a circle with a diameter of 6cm?
The exact area = pi*32 or 9*pi square cm
What is the volume of a cylinder with a radius of 9 cm and a height of 8 cm?
648pi. (pi = 3.14159...)Area of a circle = (pi) x (radius squared)= (pi)(9 squared) = (pi)81.Area of a cylinder = area of circle x height.= (pi)81 x 8= 648(pi)
What is the circumference of a circle whose diameter is 9 cm?
A circle with a radius of 4.5 cm has a circumference of 28.27 cm
What is the circumference of a circle that is 9cm wide?
The circumference of a circle that is 9 cm wide is: 28.274 cm
