What is the area of sector of circle?
The angle of the sector is 360°, area of the sector, i.e. the Whole circle = πr2. When the Angle is 1°, area of sector = πr2/360°
How do you find the perimeter of a sector with an angle?
C = π X d (3.14159 x 10) = 31.42 (to 4 s. f.) To calculate the perimeter of an arc (part of a circle) from the angle you can calculate the fraction of the circle. = 4.19cm (to 3 s.f.) The perimeter of the whole sector is therefore 4.19 + 8 = 12.19 (4 s.f.).
What is the perimeter of a sector of a circle whose central angle is 90 degree and radius is 7 cm?
= 14 +11 = 25 cm. If the measure of sector of a circle with radius 7 cm is 90∘ , what is the perimeter of the sector?
What is the area of the radius is 11?
0.245225 square meters (m²)
What is the radius of a circle with 14 meters?
The diameter of a circle is the distance from one edge to the other, passing through the center. It is twice the radius….Diameter of a Circle.

What is the area of the radius is 3?
A circle of radius = 3 or diameter = 6 or circumference = 18.85 meters has an area of: 2.827 × 10-5 square kilometers (km²)
What is the radius of 12 cm?
So, if d=12 cm, r=12(12)=122=6 cm.
What is the area of 12 cm diameter?
70.1221 square inches (in²)
What is the diameter of 12?
