2 answers:

8 0

Area of a circle = π × r²

Diameter = 2 × r

Therefore, you need to half the diameter so you can work out the area of the circle.

12 ÷ 2 = 6

Now that you have the radius (6), you can work out the area:

π × 6² = 113.097336 in²

Point C ∈ AB , AB = 30m. Point C is 1.5 times farther from point A than from point B. Find AC and CB.

Shtirlitz [24]

let's say that C is "x" units farther from B, that means that CB = x, and therefore AC = 1.5x.

$\bf \underset{\leftarrow ~~30~~\to}{\boxed{A}\stackrel{1.5x}{\rule[0.35em]{18em}{0.25pt}}C\stackrel{x}{\rule[0.35em]{10em}{0.25pt}}\boxed{B}}
\\\\\\
AB=AC+CB\implies \stackrel{AB}{30}=\stackrel{AC}{1.5x}+\stackrel{CB}{x}\implies 30=2.5x
\\\\\\
\cfrac{30}{2.5}=x\implies 12=x
\\\\[-0.35em]

AC=1.5(12)\implies AC=18~\hspace{8em} CB=x\implies CB=12$
