WebFeb 3, 2024 · Top Answerer. Divide the volume by the length to get the cross-sectional area. Assuming this is a regular hexagon, use the area formula to solve for the width of a side: A = (0.385) (s²). Multiply the side width thus calculated by the length of the prism. That gives you the area of one side.
WebFeb 14, 2024 · To calculate the area of the sector of a circle, you can use two methods. If you know the radius: Convert the central angle into radians: α [rad] = α [deg] · π/180° Multiply the radius by the angle in radians. Divide … WebAnd in this kind of figure, we have a couple of circles, one having radius R and other having radius as r. Now you can calculate area of a shape like an annulus by subtracting the area of the smaller circle from that of the bigger one. Area of an Annulus = \piR2– \pir2. Area of an Annulus = π(R2– r2)
WebIf you know the arc length and the radius, then the angle that is subtended by the sector is θ = L / r where L= arc length and r = radius (Angle in radians, of course.) Thus, the area of the sector would be: A = (θ / 2π) (π r²) A = ½ θ r² Now, we plug in the formula for θ A = ½ (L/r) r² A = ½ r L 1 comment ( 4 votes) Upvote Downvote Flag more
