What is the area of a quadrant if the radius is 7cm?

38.5 square cm
Therefore, the area of the quadrant of the circle with a radius of 7 centimeter is 38.5 square cm.

How do you find arc length with radius and area?

Radius and the sector area: Multiply the sector area by 2. Then divide the result by the radius squared (the units should be the same) to get the central angle in radians. Multiply the central angle by the radius to get the arc length.

What is the perimeter of quadrant with radius 7 cm?

∴ Perimeter of the quadrant is 25 cm.

How do you find the arc length of a quadrant?

Since a quadrant is a quarter of a circle, to find the length of the curved part, take the circumference from the last step and divide it by 4. This helps to make it clear how the solution works, but you can also calculate 0.5 × π​r​ to do this all in one step. The result of this is the length of the curved section.

What is the perimeter of a semicircle whose radius is 7cm?

If the radius of a semicircle is 7 cm, the perimeter can be calculated with the help of the formula: Perimeter = (πr + 2r), where ‘r’ is the radius and π is equal to 22/7. On substituting the values we get, Perimeter = (πr + 2r) = (22/7 × 7) + (2 × 7) = 22 + 14 = 36 cm.

What is the area of quadrant?

that is, pi (π) multiplied by the radius squared (r2). Now, to calculate the area of a quadrant, divide the area of a circle by 4 (as four quadrants make a circle). We get, Area of a quadrant, A= (πr2)/4 Square units.

What is the formula of perimeter of quadrant?

the perimeter (p) of a quadrant with straight sides of length (r) using the formula: p = 0.5πr + 2r.

How do you find the radius of a quadrant?

To find the radius when you are given the area of the quarter circle, multiply the given area by 4, then plug this number in for A into the formula A = pi * r^2 and then solve for r.

What is the perimeter of 7cm?

Each side of a square has the same length. There are 4 sides and each side is 7cm, so the perimeter is 4*7cm, or 28cm.

What is the area of the quadrant if the radius is 7cm?

A quadrant is ¼ of the circle so the area of the quadrant is 154/4 or 38.5 cm^2. The circumference would be 44/4 or 11 cm. If the radius of a quadrant is 7 cm, what is the area, arc length, and perimeter? Area of the quadrant = 1/4 area of a circle with a radius of 7 cm.

How do you find the area of a circle with radius?

You can also find the area of a sector from its radius and its arc length. The formula for area, A A, of a circle with radius, r, and arc length, L L, is: A = (r × L) 2 A = (r × L) 2

How do you find the perimeter of a circle?

The perimeter should be calculated by doubling the radius and then adding it to the length of the arc. Perimeter of a Sector Formula The formula for the perimeter of the sector of a circle is given below : Perimeter of sector = radius + radius + arc length

How do you find the area of a sector with arc length?

Arc Length and Sector Area You can also find the area of a sector from its radius and its arc length. The formula for area, A A, of a circle with radius, r, and arc length, L L, is: A = (r × L) 2 A = (r × L) 2
