Question

the radius and height of a cylinder are in the ratio4:7 And its volume is 1188cm find its radius

Answer 1

here is ur answer ➖➖➖➖➖➖➖⬇

Radius and height are in the ratio 4:7
let radius, r = 4x
height, h = 7x

volume = πr²h
⇒ 1188 = π × (4x)² × 7x
⇒ 1188 = (22/7) ×16x² × 7x
⇒ 1188 = 22×16x² × x
⇒ 1188 = 352x³
⇒ x³ = 1188/352 = 27/8
⇒ x = ∛(27/8) = 3/2 = 1.5cm

radius = 4x = 4×1.5 = 6cm
height = 7x = 7×1.5 = 10.5 cm

TSA = 2πr(r+h)
        = 2×(22/7)×6(6+10.5)
        = 836.28 cm²

hope it helps uhh....

please mark as a brainliest ✌☺

Answer 2

ratio of radius and height=4:7
r/h=4/7
height=10.5 cm
