Measurement- Perimeter and Area

Front

What is the formula for the circumference of a circle?

Back

The formula for the circumference (C) of a circle is given by C = 2πr, where r is the radius.

Front

How do you calculate the perimeter of a rectangle?

Back

The perimeter (P) of a rectangle is calculated using the formula P = 2(l + w), where l is the length and w is the width.

Front

What is the area of a rectangle?

Back

The area (A) of a rectangle is calculated using the formula A = l × w, where l is the length and w is the width.

Front

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

Back

The circumference of a circle is directly proportional to its radius. As the radius increases, the circumference increases.

Front

What is the formula for the area of a circle?

Back

The area (A) of a circle is given by A = πr², where r is the radius.

Front

If a rectangle has a length of 10 inches and a width of 5 inches, what is its perimeter?

Back

The perimeter is P = 2(10 + 5) = 30 inches.

Front

If a circle has a radius of 3 cm, what is its circumference?

Back

The circumference is C = 2π(3) = 6π cm.

Front

What is the perimeter of a square with a side length of 4 cm?

Back

The perimeter of a square is P = 4s, where s is the side length. So, P = 4(4) = 16 cm.

Front

How do you find the area of a triangle?

Back

The area (A) of a triangle is calculated using the formula A = 1/2 × base × height.

Front

What is the difference between perimeter and area?

Back

Perimeter is the total distance around a shape, while area measures the space inside a shape.
