Question

write the formula used to calucalate the total surface area of a hemispherical solid of radius 'r'​

Answer 1

Answer:

Total surface area of a hemispherical shell can be found using the formula, TSA = 2π (r2 r 2 2 ;+ r1 r 1 2) + π(r2 r 2 2 – r1 r 1 2) (or) 3 π r2 r 2 2 + π r1 r 1 2, where, r1 r 1 is the radius of internal hemispherical shell, and r2 r 2 is the radius of external hemispherical shell

Answer 2

Step-by-step explanation:

TSA = 2π (r2 r 2 2 ;+ r1 r 1 2) + π(r2 r 2 2 – r1 r 1 2) (or) 3 π r2 r 2 2 + π r1 r 1 2,
