Answer:

Radius = 2.8

Explanation:

V = 1⁄3 πr² × h

50 = 1⁄3 πr² × 6

50 = 1⁄3 × 22⁄7 × r² × 6

50 = 22⁄21 × r² × 6

50 = 22⁄21 × 6 × r²

50 = 6.286 × r²

50 = 6.286r²

50/6.286 = 6.286r²/6.286

r² = 7.954

r = √7.954

r = 2.820

Answer:

radius r = 2.82094792 m

height h = 6 m

slant height s = 6.63006389 m

volume V = 50 m3

lateral surface area L = 58.7574113 m2

base surface area B = 25 m2

total surface area A = 83.7574113 m2
