WebJan 9, 2024 · In general, the area of some part of the surface of an object is called the surface area. An entire object may have many different flat surfaces (as in a cube) that have to be measured separately. WebIf I understand your description correctly, we can figure out the area as follows: A rough estimate (taking the width as 8 instead of 7, which gives a half-circle) gives π r l = 96 π ≈ 300. tan θ = 4 3.5, r sin θ = 4 2 + ( 3.5) 2 2. Since sin θ = 4 4 2 + ( 3.5) 2, we have r = 4 2 + ( 3.5) 2 8 = 113 32. θ = arctan 4 3.5 ≈ 0.85917. WebApr 12, 2024 · Earth’s Surface Area.
