What is the angle subtended at the Centre of a circle of radius 7cm?
Radius of a circle is 7cm and angle subtended at the center is 60∘.
What is perimeter of a sector of radius 7 cm and the angle subtended by the arc at the Centre 600?
Correct Answer: B) 22.8 cm. =72360×2×227=445 cm.
What is the length of an arc of a circle of radius 7cm if the angle subtended by it at the Centre is 60?
length of arc = theta πr/180°.
What is the length of an arc of a circle of radius 7 cm?
22 cm
In a circle with a radius of 7 cm, an arc of the circle has length 22 cm.
What is the area of the sector with radius 7 cm and the angle at the center is 600?
Thus, the area of sector of a circle is equal to 25.67 .
What is the angle subtended at the Centre of a circle?
The angle subtended at the centre of the circle is 90° .
What is the measure of semicircular arc?
180°
The full arc of a semicircle always measures 180° (equivalently, π radians, or a half-turn).
What is the area of the sector whose radius is 7 cm and angle 180 degrees?
Therefore,area of sector is 77 cm².
What is the area of sector having radius 7 cm and angle at the center is 30?
∴ Area of the sector is 89.83 cm2 .
What is the angle subtended at the center of a circle of radius 6 cm by arc of length 6π cm?
Answer: The angle subtended at the centre of the circle is 90° . Hence, the angle subtended at the centre of the circle is 90° .
What is the angle subtended at the centre of a circle of radius 6 cm by an arc of length 2π cm?
Answer: angle subtended at the centre = L/r =3pie/6 =pie/2= 90°….. so the angle subtended is 90°at the centre.
How to find the length of the arc of a circle?
Radius of a circle is 7 cm and the angle subtended at the centre of 60 degree find the length of the arc? Use the formula: s = r θ, where s is the length of an arc of a circle with radius r and θ (in radians) is the angle subtended by the arc of lengh s at the center of the circle. θ being in radians units of s and r are same.
What is the radius of a circle with a central angle 123?
Let’s try inputting degrees again. 2b) A circle’s arc length is 4.9 with a central angle of 123 degrees. What is the radius? Click the “Radius” button, enter arc length = 4.9 then click the “DEGREES” button. Enter central angle =123 then click “CALCULATE” and your answer is Radius = 2.2825.
How do you calculate the radius of a circle in Excel?
Click the “Radius” button, input arc length 5.9 and central angle 1.67. Click “CALCULATE” and your answer is radius = 3.5329. Let’s try inputting degrees again. 2b) A circle’s arc length is 4.9 with a central angle of 123 degrees.
What is the arc of 360 degrees around a circle?
36° is 1/10th of 360°, so arc will be 1/10th or 0.1 of the circumference of the same circle.
