Answer:

Step-by-step explanation:

The scale factor of an area is the square of the scale factor of a length.

The scale for lengths is 1 cm : 3 m.

You now square that scale to get the scale of the areas.

Scale of areas:

(1 cm)^2 : (3 m)^2

1 cm^2 : 9 m^2

The ratio of the measures of the three angles is 4:5:6. Find the measure of each angle of the triangle

Furkat [3]

Answer:

Let the number be x.

Given the statement: The ratio of the measure of the three angles is, 4 : 5 : 6.

Then, the angles be 4x , 5x and 6x respectively.

We know that: The sum of all the measures of angles is 180 degree.

then;

$4x+5x+6x = 180^{\circ}$

Combine like terms;

$15x = 180^{\circ}$

Divide by 15 both sides we get;

$x = 12$

Then, the measure of each angle of triangle:

$4x = 4(12) = 48^{\circ}$

$5x = 5(12) = 60^{\circ}$

$6x = 6(12) = 72^{\circ}$

The diameter of a circle is 14 inches, Eind the circumference and area. Use<br> Find<br> 22 for it.

snow_lady [41]

Answer:

Step-by-step explanation:

If diameter is 14 inches radius = d/2 = 14/2 = 7 inches

Circumference = 2 pi R = 2 × 22/7 × 7

= 44 inches

Area = pi R square = 22/7 × (7)^2

=22/7 × 49

= 154 inches

Hope this helps
