What is the area with a radius of 5?
Summary: The area of a circle with a radius of 5 is 25π sq.
What is area of circle if radius is 5cm?
Answer: The area of the circle with a radius of 5 cm is 78.5 cm2.
What is the area of a sector of a circle of radius 5?
The area of a sector is given by the formula, lr2, where l is the length of an arc and r is the radius of the circle. Thus the area of the sector of length 3.5 cm formed by the circle of radius 5 cm is 8.75 cm2.
What is the equation of a circle with radius 5?
Let the equation of the required circle be (x – h)2 + (y – k)2 = r 2. Since the radius of the circle is 5 and its centre lies on the x-axis, k = 0 and r = 5. Now, the equation of the circle becomes (x – h)2 + y2 = 25. It is given that the circle passes through the point (2, 3).

What is the area of radius 4?
16π square units
Given that radius of the circle is 4 units. So, the area of circle = πr2 = π(4)2 = 16π square units. Thus, the area of a circle with a radius of 4 units is 16π sq. units.
What is arc formula?
The formula to measure the length of the arc is – Arc Length Formula (if θ is in degrees) s = 2 π r (θ/360°) Arc Length Formula (if θ is in radians) s = ϴ × r.
What is the area of sector of a circle?
The formula for the area of the sector of a circle is 𝜃/360o (𝜋r2) where r is the radius of the circle and 𝜃 is the angle of the sector.
How do I find the area of a circle?
The area of a circle is pi times the radius squared (A = π r²).
What is the standard form of center at origin radius 5?
The point on the circle centered at the origin with a radius of 5 units is (2 , √21).
What is the area of radius 7?
Area of given circle=722×72=22×7=154sq.cm.

How do you find the area with the radius?
To find the area using the radius, or the length from the center of the circle to the edge, use the formula area = πr^2, where r is the radius. For example, if the radius of the circle is 6 inches, first you would square 6 and get 36. Then, you would multiply 36 by π and get 113.04.

What are the formulas for circles?
Circle Formulas in Math :
- Area of a circle (A ) = π r 2 =( π/4 ) D2 = 0.7854 D2
- Diameter of a circle (D) = √(A/0.7854).
- The area of the sector = (θ/2) r 2
- Sector angle of a circle θ = (180 x l )/ (π r ).
- Perimeter of the segment = (θ π r / 180) + 2r sin (θ/2).
- Area of a circular ring = π (R 2 – r 2 ).
