Answer:

C. 125 : 1

Step-by-step explanation:

V(A) : V(B) = [r(a)]³ : [r(b)]³ = 15³ : 3³ = (5*3)³: 3³ = (5³*3³) : 3³ = 5³ : 1 = 125:1

Lisa drew three circles to form a figure. The areas of the circles were in the
Tamiku [17]

Answer:

Fraction of the figure shaded = \frac{13}{16}

Step-by-step explanation:

Ratio of the areas of the given circles are 1 : 4 : 16

Then the radii of the circles will be in the ratio = \sqrt{1}:\sqrt{4}:\sqrt{16}

                                                                             = 1 : 2 : 4

If the radius of the smallest circle = x units

Then the radius of the middle circle = 2x units

and the radius of the largest circle = 4x units

Area of the smallest circle = πx²

Area of the middle circle = π(2x)² = 4πx²

Area of the largest circle = π(4x)²= 16πx²

Area of the region which is not shaded in the middle circle = πx²(4 - 1)

                                                                                                  = 3πx²

Therefore, area of the shaded region = Area of the largest circle - Area of the region which is not shaded

= 16πx² - 3πx²

= 13πx²

Fraction of the figure which is not shaded = \frac{\text{Area of the shaded region}}{\text{Area of the largest circle}}

= \frac{13\pi x^{2} }{16\pi x^{2} }

= \frac{13}{16}
