Answer: Im not too good at math but I will try to help and I will say 70 is the answer...?
Im really sorry if I get this wrong
Original coordinates of the points:
A (8,15) ; B (12,13) ; C (8,10)
Dilated scale factor of 3.
A ⇒ 3x = 3(8) = 24 ; 3y = 3(15) = 45 ⇒ A' (24,45)
B ⇒ 3x = 3(12) = 36 ; 3y = 3(13) = 39 ⇒ B' (36, 39)
C ⇒ 3x = 3(8) = 24 ; 3y = 3(10) = 30 ⇒ C' (24, 30)
The given image forms a right triangle. So, I'll get the short leg and long leg of the right triangle to solve for the hypotenuse, length of CB.
Short leg: y value of B and C
39 - 30 = 9
Long leg: x value of B and C
36 - 24 = 12
a² + b² = c²
9² + 12² = c²
81 + 144 = c²
225 = c²
√225 = √c²
15 = c
The length of CB is 15 units.

Answer:
31.4 is the answer
Step-by-step explanation:
The area of the circle is approximately 50
<h3>Areas</h3>
The area of a shape is the amount of space occupied by the shape
<h3>Area of circle</h3>
Given the three radius of the circle, the area of the triangle is calculated using:
From the figure, we have:
--- the radius
So, we have:
Approximate
Hence, the area of the circle is approximately 50
