A biker cycles 9 miles in 2 3 of an hour.
Aloiza [94]

Answer:

2 hours: 27 miles, 3 hours: 40.5 miles, 3.5 hours: 47.25 miles

Step-by-step explanation:

1.) If a hiker hikes 9 miles in 2/3 of an hour, he will hike 4.5 (Half of 2/3 is 1/3 and half of 9 is 4.5) miles in 1/3 of an hour and 13.5 miles per hour. (1/3 times 3 gives us a whole and 4.5 times 3 is 13.5)

2.) 2 hours: 13.5 * 2 = 27 miles

3.) 3 hours: 13.5 * 3 = 40.5 miles

4.) 3.5 hours: 13.5 * 3.5 = 47.25 miles

find the area of the shaded region of circle y below. Round your answer to the nearest tenth if necessary
S_A_V [24]

Answer:

  285.6 square units

Step-by-step explanation:

The shaded area can be described a a whole circle less a 90° segment, or as a 3/4 circle with a right triangle added. The formula for the segment area is that of a sector less the triangle, so the computation is the same either way.

__

<h3>3/4 circle area</h3>

The area of a circle is given by ...

  A = πr²

so 3/4 of a circle is 3/4 this value:

  3/4 circle area = (3/4)(π)(10²) = 75π . . . . square units

<h3>Triangle area</h3>

The area of the isosceles right triangle is given by ...

  A = 1/2s²

  A = 1/2(10²) = 50 . . . . square units

<h3>Shaded area</h3>

The shaded area is the sum of these two ...

  shaded area = 3/4 circle area + right triangle area

  shaded area = 75π + 50 ≈ 285.6 . . . . square units
