WebFind the area of a sector of a circular region whose central angle is 3 radians with a radius of 5 feet. Solution: The radius of sector = r = 5 feet Angle of sector = θ = 3 radians If is measured in radians, then The area of the sector = θ 2 × r 2 = 3 2 × 5 2 = 37.5 sq. feet.

Radius to Circumference of Circle Calculator - SensorsONE

WebTo find the circumference of a circle with a given radius, we use the formula: Circumference π = 2 × π × radius where π is the mathematical constant pi, approximately equal to 3.14159. Substituting the given radius of 6,371 into this formula, we get: Circumference π = 2 × π × 6,371 Webif the diameter is given we find the circumference by diameter x pi, so if the radius is half the value of the diameter then if you are only given the radius we find the … Web5 jul. 2024 · For part a, it asks us to find dr/dt when r = 3 cm. Plugging everything in, we're able to find: dA/dt = 2 π*r (dr/dt) 6 = 2* π *3 ( dr/dt) 6 = 6 π (dr/dt) 1/π = dr/dt So our radius is changing at a rate of 1/ π cm/s. For part b, we are told that the circumference is 4 cm. editing on xbox
