Answer:
Option A. 
Step-by-step explanation:
we know that
A perfect square trinomial is equal to
In this problem we have
equate the equations and solve for a
so
therefore
the perfect square trinomial is equal to 
First find 10%
(1200 divided by 10)
10% = £120
Then add it onto the original amount
£1200 + £120 = £1320
Answer: 360 is a complete circle meaning the figure will be back where it was originally
Step-by-step explanation:
Answer:
1) The slant height = 9.8 cm ⇒ (C)
2) The slant height = 11.4 cm ⇒ (D)
Step-by-step explanation:
1) ∵ The slant height of the cone = √[(radius)² + (height)²]
∵ Diameter = 8 cm
∴ Radius = 4 cm
∵ Height = 9 cm
∴ Slant height = √(4² + 9²) = √97 = 9.8 cm ⇒ (C)
2) ∵ The slant height of the cone = √[(radius)² + (height)²]
∵ Diameter = 18 cm
∴ Radius = 9 cm
∵ Height = 7 cm
∴ Slant height = √(9² + 7²) = √130 = 11.4 cm ⇒ (D)
$2.80 each because when you divide 9 by 25.20, you get 2.8.
