Answer:
x = - 9
Step-by-step explanation:
Given
= - 3 ( multiply both sides by 3 to clear the fraction )
x = - 9
Answer:
15π cm²
Step-by-step explanation:
The total lateral area of a cone
= πr√h² + r²
= √h² + r² = l
h = Height = 4cm
r = radius = 3cm
Hence:
= π × 3 √4² + 3²
= 3π × √16 + 9
= 3π × √25
= 3π × 5
= 15π cm²
