Answer:
1306.90≅ 1307 rounded to the nearest tens
Step-by-step explanation:
r= radius = 13 cm
l is the slant height =19 cm
surface area of the cone= area of the circle + area of the curved of the cone
SA=πrl +πr²
SA=π(13)(19) +169π
SA= 247π +169π= 416π=1306.90≅ 1307 rounded to the nearest tens
Answer:
factored form
Step-by-step explanation:
example
(x + 2)(x + 3) ← is an expression in factored form
= x² + 5x + 6 ← in expanded form
