Question

Kak minta bantuannya ya kak,,,,,
sekaligus jalannya ya kak,,,,
THANKS A LOT

Answer 1

1.L.p = 4.Π.r²
803,84 = 4.3,14.r²
r² = 803,84 ÷ 4×3,14
r²=803,84÷12,56
r² = 64
r = √64
r = 8

v = 4/3.Π.r³
= 4/3.3,14.8³
= 2143,57 cm³

2. v= 4/3.Π.r³
= 4/3.3,14.3³
= 113,04 cm³

3.v = 4/3.Π.r³
288Π= 4/3.r³
r³ = 288×3/4
r³ = 216
r = √216
= 6 cm
