What is the area of a circle radius equal to 2?
Using 3.14 as Pi the area of circle is: 12.56
What is the circumference of circle if the radius is 48?
The circumference C of any circle is equal to pi*diameter. The diameter is equal to the radius times 2. So, for a circle with radius 48, it has a diameter of 96, and a circumference of 96*3.14=301.44. This of course is using 3.14 as an estimate for pi.
Why area of circle equals 3.14rr?
The area of a circle is calculated using the formula A = πr², where A represents the area and r is the radius. The constant π (pi) is approximately equal to 3.14, which represents the ratio of a circle's circumference to its diameter. This formula arises from the concept that the area can be visualized as the number of square units that can fit within the boundary of the circle, with the radius squared reflecting the scaling of these units as the radius increases.
What with the circumference be of a circle that has 7 cm radius?
The circumference of a circle can be calculated using the formula ( C = 2\pi r ), where ( r ) is the radius. For a circle with a radius of 7 cm, the circumference would be ( C = 2\pi(7) ), which equals approximately ( 43.98 ) cm when using ( \pi \approx 3.14 ).
What is the circumference of a circle if the radius is 49?
The circumference of a circle can be calculated using the formula ( C = 2\pi r ), where ( r ) is the radius. If the radius is 49, the circumference would be ( C = 2\pi \times 49 ), which equals approximately 307.76 when using ( \pi \approx 3.14 ). Thus, the circumference of the circle is about 307.76 units.
What is the area of a circle which has a radius equal to 1?
The area of a circle can be calculated using the formula pi*(radius^2). So in this case, the area of the circle will be pi*(1^2), which is equal to pi.
What is the area of a circle radius equal to 2?
Using 3.14 as Pi the area of circle is: 12.56
What is the circumference of circle if the radius is 48?
The circumference C of any circle is equal to pi*diameter. The diameter is equal to the radius times 2. So, for a circle with radius 48, it has a diameter of 96, and a circumference of 96*3.14=301.44. This of course is using 3.14 as an estimate for pi.
Why area of circle equals 3.14rr?
The area of a circle is calculated using the formula A = πr², where A represents the area and r is the radius. The constant π (pi) is approximately equal to 3.14, which represents the ratio of a circle's circumference to its diameter. This formula arises from the concept that the area can be visualized as the number of square units that can fit within the boundary of the circle, with the radius squared reflecting the scaling of these units as the radius increases.
How do you divide a circle into 8 equal parts using 3 lines?
Draw two diameters perpendicular to each other. Draw a smaller circle with the same centre such that the radius of the inner circle is 'r' and the radius of the outer circle is 'r√2.' [Or, the radius of the outer circle is R and the radius of the inner circle is R/√2.]
What with the circumference be of a circle that has 7 cm radius?
The circumference of a circle can be calculated using the formula ( C = 2\pi r ), where ( r ) is the radius. For a circle with a radius of 7 cm, the circumference would be ( C = 2\pi(7) ), which equals approximately ( 43.98 ) cm when using ( \pi \approx 3.14 ).
What is the formula using pi for the area of a circle?
area of a circle is equal to pi times the square of its radius.. A=(pi)r^2
What is the circumference of a circle if the radius is 49?
The circumference of a circle can be calculated using the formula ( C = 2\pi r ), where ( r ) is the radius. If the radius is 49, the circumference would be ( C = 2\pi \times 49 ), which equals approximately 307.76 when using ( \pi \approx 3.14 ). Thus, the circumference of the circle is about 307.76 units.
What is the circumference of a 11 cm radius?
The circumference of a circle can be calculated using the formula ( C = 2\pi r ), where ( r ) is the radius. For a circle with an 11 cm radius, the circumference is ( C = 2\pi(11) ), which equals approximately 69.44 cm when using ( \pi \approx 3.14 ).
What is the area of circle by using 3.14?
Area = (3.14) x (radius) x (radius) "Radius" means the distance from the center of the circle out to the circle's curved line.
What is the area of a circle with the radius of 100?
The area of a circle can be calculated using the formula A = πr^2, where A is the area, π is a constant approximately equal to 3.14159, and r is the radius of the circle. Given a radius of 100, the area of the circle would be A = π(100)^2 = 10000π square units. This simplifies to approximately 31415.9 square units.
What is the circumstance if the radius is 21?
The circumstance of a circle is typically referred to as its circumference, which can be calculated using the formula ( C = 2\pi r ), where ( r ) is the radius. If the radius is 21, the circumference would be ( C = 2\pi \times 21 ), which equals approximately 131.95 when using ( \pi \approx 3.14 ). Thus, the circumference of a circle with a radius of 21 is about 131.95 units.
