Use the image to answer the question.
An illustration shows a triangle with a base labeled 8 inches. A line runs through the center of the triangle from the apex to the base. This perpendicular height is labeled 5 inches.

Crystal cuts a piece of wood into the shape of a triangle. The height of the triangle is 5 inches, and the base of the triangle measures 8 inches. Crystal makes a scale drawing of the triangle. If the height of her scale drawing is 2 inches, what is the area of her scale drawing?

6.4 square inches

To find the area of the scale drawing, you need to calculate the scale factor by comparing the height of the original triangle to the height of the scale drawing. The scale factor is 5/2 = 2.5.

Then, the area of the scale drawing would be (8 * 2) / 2 = 8 square inches * scale factor (2.5) = 20 square inches.

To find the circumference of a circle, you use the formula:

Circumference = 2 * π * r

Given that the radius, r, is 90 and using π = 3.14:

Circumference = 2 * 3.14 * 90
Circumference = 565.2

Therefore, the approximate circumference of a circle with a radius of 90 is 565.2 units.

To find the circumference of a circle when you are given the diameter, you can use the formula:

Circumference = π * diameter

Given that the diameter is 379 and using π = 3.14:

Circumference = 3.14 * 379
Circumference = 1190.26

Therefore, the approximate circumference of a circle with a diameter of 379 is 1190.26 units.

To find the diameter of a circle when you are given the circumference, you can use the formula:

Circumference = π * diameter

Given that the circumference is 7,459 miles and using π = 3.14:

7,459 = 3.14 * diameter

Now, solve for the diameter:
diameter = 7,459 / 3.14
diameter ≈ 2371.974

Rounded to the nearest hundredths place, the diameter of the circle is approximately 2371.97 miles.

To find the area of a circle, you use the formula:

Area = π * radius^2

Given that the radius is 98 mm and using π = 3.14:

Area = 3.14 * 98^2
Area = 3.14 * 9604
Area = 30192.56

Therefore, the area of the circle with a radius of 98 mm is 30192.56 square millimeters.
