The nest step is to Construct the altitude from the incenter to a side of the triangle and label the intersection point. (: but next time I'd highly recommend (if you can) add an attachment describing your question, hope this is helpful though.

The ratio of the area of the shaded part to the unshaded part is______.
elena-14-01-66 [18.8K]

Answer: 1 : 3

Shaded area:

\Longrightarrow \sf  Length \ \times \  Breadth = \dfrac{x}{4}  \ \times \ x  \ = \ \dfrac{1}{4}x^2

Unshaded area:

\Longrightarrow \sf  Length \ \times \  Breadth = (x  - \dfrac{x}{4}) \ \times \ x  \ = \ \dfrac{3}{4}x^2

Ratio of shaded to unshaded:

\Longrightarrow \sf \dfrac{1}{4} x^2 \ : \ \dfrac{3}{4} x^2  =  1 : 3 \quad (simplified)

What is the approximate volume of the cylinder? Use 3.14 for π. Cylinder with height of 22 centimeters and radius of 9 centimete
mamaluj [8]

The volume of a cylinder is found through the following formula:


V = \pi r^2 h


We already have all of our values needed for this formula, so plug them into the equation:


\pi = 3.14

r = 9

h = 22


V = (3.14)(9)^2(22)

9^2 = 9 \times 9 = 81

3.14 \times 81 \times 22 = \boxed{5595.48}


Rounded to the nearest ones value, the approximate volume of the cylinder will be 5595 cubic centimeters.

If you could travel 450 miles in 5.5 hours, then how far could you travel in 7 hours?​
GrogVix [38]

Answer:

I will use x as the distance traveled in 7 hours

450/5.5 = x/7.7 - set up proportion

5.5x = 3465 - cross products

5.5x/5.5 = 3465/5.5 - divide each side by 5.5

x = 630 - answer

hope this helps.

Estimate the perimeter and the area of the shaded figure to the nearest whole number.
soldier1979 [14.2K]

Answer:

Step-by-step explanation:

The area and perimeter of the given shaded figure are respectively 33.12 unit² and 20.56 units.

Area and perimeter-based problem:

What information do we have?

Radius of semi-circle = 8 / 2 = 4 unit

Length of remain Rectangle = 8 unit

Width of remain Rectangle = 2 unit

Perimeter of shaded figure = πr + (l + 2b)

Perimeter of shaded figure = (3.14)(4) + [4 + (2)(2)]

Perimeter of shaded figure = 12.56 + 4 + 4

Perimeter of shaded figure = 20.56 units

Area of shaded figure = πr²/2 + lb/2

Area of shaded figure = (3.14)(4)²/2 + (8)(2)/2

Area of shaded figure = (3.14)(8) + 8

Area of shaded figure = 25.12 + 8

Area of shaded figure = 33.12 unit²
