The circumference of a circle is 16π inches. Show how you can use this information to calculate the same circle’s area.

Mathematics
1 answer:
Temka [501]3 years ago
5 0

Answer:

A = 64 pi inches ^2

Step-by-step explanation:

Circumference is equal to

C =2*pi*r  where r is the radius

16 pi = 2 * pi *r

Divide each side by 2 pi

16pi/2pi = 2pir/2pi

8 = r

The radius is 8

To find the area, we use

A = pi r^2

   =pi (8)^2

  = 64 pi

A right-angled triangle has one side of length 1.5 cm. Its hypotenuse is 6 cm. How long is its other side?
irga5000 [103]

Answer:

Step-by-step explanation:

pythagorean theorem. a^2+b^2=c^2

1.5^2+b^2=6^2

2.25+b^2=12

12-2.25=b^2

b^2=9.75

take the square root

b=3.12

The graph function g(x) is a transformation of the graph of function f(x)=x^2. g(x)=
emmasim [6.3K]
<span>A)2x^2+3   is a transformation of f(x)=x^2:  Stretch the graph vertically by a factor of 2 and then shift the entire resulting graph up by 3 units.  The graph will still look like a parabola that opens up.

</span>B)-2x^2-3   is a transformation of f(x)=x^2:  Stretch the graph vertically by a factor of 2, reflect the resulting graph in the x-axis, and then shift the entire resulting graph down by 3 units.  The graph will still look like a parabola that opens down.

Answers to C and D are very similar, except that we compress the graph of x^2 v ertically by a factor of (1/2).

None of these A, B, C, D is wrong.

Plz I need help with geometry homework FIND THE ANGLES
Talja [164]

Answer:

  1. a = 36°
  2. b = 36°
  3. c = 72°
  4. d = 72°
  5. e = 108°
  6. f = 16°
  7. g = 74°
  8. h = 70°

Step-by-step explanation:

You are expected to know and make use of the following relations:

  • vertical angles are congruent
  • angles of a linear pair are supplementary
  • angles of a triangle sum to 180°
  • alternate interior angles are congruent (at parallel lines)
  • corresponding angles are congruent (at parallel lines)
  • acute angles of a right triangle are complementary
  • base angles of an isosceles triangle are congruent

__

For this problem, it isn't always easiest to work the questions in order. It is best to start with the angles easiest to find from those given.

  b and 144° are a linear pair, so b = 180° -144° = 36°

  a and b are alternate interior angles, so a = b = 36°

  2d and 144° are corresponding angles, so d = 144°/2 = 72°

  e is the apex angle of an isosceles triangle with base angles 36°, so is 180° -2(36°) = 108° = e

  f and 164° are a linear pair, so f = 180° -164° = 16°

  g and f are complementary, so g = 90° -16° = 74°

  g+h is a vertical angle with 144°, so is congruent to that. h = 144° -74° = 70°

  c is the base angle of an isosceles triangle with b as the vertex angle. That means c = (180° -36°)/2 = 72°
