What is a circle's diameter if the radius is 7 cm?
The diameter of a circle is double the radius. So a circle with a radius of 7 cm has a diameter of 14 cm.
What is the radius of a circle if the area is 153.86cm2?
To find the radius of a circle when given the area, you can use the formula A = πr^2, where A is the area and r is the radius. Given that the area is 153.86 cm^2, you can plug this value into the formula and solve for r. 153.86 = πr^2 r^2 = 153.86 / π r = √(153.86 / π) ≈ √49 ≈ 7 cm Therefore, the radius of the circle is approximately 7 cm.
What is the area of a circle if the radius equals 15 cm?
area=pi*r*r area=(22/7)*15*15 area=707.14 square cm
How can you find area of a circle whose circumference is 44cm?
Radius of circle: 44/2*pi = 7 rounded Area of circle: pi*7 squared = 154 square cm rounded
What is the area of a circle if its circumference is 14π?
Circumference is 2π times the radius. So, for 14π the radius is 7. Area is πr2, so the area of a circle with radius 7 is 72π, or 49π (153.93).
What is the area of a circle that has a radius of 7 cm?
The area is 154 cm2
What is a circle's diameter if the radius is 7 cm?
The diameter of a circle is double the radius. So a circle with a radius of 7 cm has a diameter of 14 cm.
If the circumference of a circle is 44 cm then what is its area?
Radius of circle: 44/(2*pi) = 7 cm rounded Area of circle: pi*7^2 = 154 square cm rounded
What is the area of a circle with the radius 5 cm?
the square root of 7
What is the radius of a circle if the area is 153.86cm2?
To find the radius of a circle when given the area, you can use the formula A = πr^2, where A is the area and r is the radius. Given that the area is 153.86 cm^2, you can plug this value into the formula and solve for r. 153.86 = πr^2 r^2 = 153.86 / π r = √(153.86 / π) ≈ √49 ≈ 7 cm Therefore, the radius of the circle is approximately 7 cm.
What is the area of a circle with a radius of 28 cm Use the approximation of 22 by 7 as pie?
Area = 22/7*282 = 2464 square cm
What is the diameter of a circle whose radius is 7 cm?
14 cm. In a circle, diameter is always twice the radius.
What is the radius of a circle with a diameter of 7 cm?
it is 3.5 cm
What is the area of a circle if the radius equals 15 cm?
area=pi*r*r area=(22/7)*15*15 area=707.14 square cm
How can you find area of a circle whose circumference is 44cm?
Radius of circle: 44/2*pi = 7 rounded Area of circle: pi*7 squared = 154 square cm rounded
Which has the greatest area a circle with a radius of 4 cm or a semi-circle with a diameter of 11 cm?
-7
What is the length of a diameter of a circle with a radius of 7 cm?
14 cm
