WebThe curved surface area of a hemisphere with radius, say 'k', can be calculated using the formula mentioned below: CSA of a hemisphere = 1/2 (CSA of a perfect sphere from which the hemisphere is carved out) = 1/2 (4 π k 2 ) = 2 π k 2. Total Surface Area of a Hemisphere (TSA) Formula. WebThings to Remember Based on Surface Area of a Cylinder. Surface Area of Cylinder (in terms of π) = 2πr (h + r) sq. unit. Curved surface area (CSA) of cylinder = 2πrh sq. units. Area of the circular bases of cylinder = 2 (πr 2) Total surface area (TSA) = 2π × r × h + 2πr 2 = 2πr (h + r) sq. units. WebWrite down the formula for the sphere. We need to consider the formula for the volume of a sphere. V=\frac {4} {3} \pi r^3 V = 34πr3. 2 Adapt the formula for the question. The formula needs to be halved for the volume of a hemisphere. V=\frac {4} {3} \pi r^3 \div 2 V = 34πr3 ÷2. 3 Substitute in the value. ptp delay timeout
