Chapter 11 Flashcardizz Review

Front

What is the formula for the surface area of a rectangular prism?

Back

Surface Area = 2(lw + lh + wh), where l = length, w = width, h = height.

Front

How do you calculate the volume of a cone?

Back

Volume = (1/3)πr²h, where r = radius and h = height.

Front

What is an annulus?

Back

An annulus is a ring-shaped object, defined as the region between two concentric circles.

Front

What is the formula for the area of a hexagon?

Back

Area = (3√3/2)s², where s = length of a side.

Front

How do you find the radius of a cone given its volume and height?

Back

Rearrange the volume formula: r = √((3V)/(πh)).

Front

What is the significance of π in geometry?

Back

π (pi) is a constant approximately equal to 3.14, representing the ratio of a circle's circumference to its diameter.

Front

What is the relationship between surface area and volume?

Back

Surface area measures the total area of the surface of a 3D object, while volume measures the space inside the object.

Front

How do you calculate the area of an annulus?

Back

Area = π(R² - r²), where R = outer radius and r = inner radius.

Front

What is the formula for the area of a triangle?

Back

Area = (1/2)bh, where b = base and h = height.

Front

What is the difference between area and perimeter?

Back

Area measures the space inside a shape, while perimeter measures the distance around a shape.
