Geo B_HW_Surface Area of Pyramids and Cones

Front

What is the formula for the surface area of a pyramid?

Back

The surface area (SA) of a pyramid is given by the formula: SA = Base Area + Lateral Area.

Front

How do you calculate the lateral area of a pyramid?

Back

The lateral area of a pyramid can be calculated using the formula: Lateral Area = (Perimeter of Base * Slant Height) / 2.

Front

What is the formula for the surface area of a cone?

Back

The surface area (SA) of a cone is given by the formula: SA = πr^2 + πrl, where r is the radius and l is the slant height.

Front

How do you find the slant height of a cone?

Back

The slant height (l) of a cone can be found using the Pythagorean theorem: l = √(r^2 + h^2), where r is the radius and h is the height.

Front

What is the relationship between the radius and diameter of a circle?

Back

The diameter (d) of a circle is twice the radius (r): d = 2r.

Front

How do you calculate the area of a square?

Back

The area (A) of a square is calculated using the formula: A = side^2.

Front

What is the Pythagorean theorem?

Back

The Pythagorean theorem states that in a right triangle, the square of the hypotenuse (c) is equal to the sum of the squares of the other two sides (a and b): c^2 = a^2 + b^2.

Front

How do you round a number to the nearest hundredth?

Back

To round a number to the nearest hundredth, look at the third decimal place. If it is 5 or greater, round up the second decimal place by one.

Front

What is the formula for the area of a triangle?

Back

The area (A) of a triangle is given by the formula: A = (base * height) / 2.

Front

What is the difference between surface area and lateral area?

Back

Surface area includes all the outer surfaces of a 3D shape, while lateral area only includes the sides, excluding the base(s).
