SA,Volume and Circle Test Review

Front

What is the formula for the area of a circle?

Back

The area of a circle is calculated using the formula: A = πr², where A is the area and r is the radius.

Front

What is the formula for the volume of a cone?

Back

The volume of a cone is calculated using the formula: V = (1/3)πr²h, where V is the volume, r is the radius, and h is the height.

Front

How do you calculate the surface area of a rectangular prism?

Back

The surface area of a rectangular prism is calculated using the formula: SA = 2lw + 2lh + 2wh, where l is length, w is width, and h is height.

Front

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

Back

The circumference of a circle is calculated using the formula: C = 2πr, where C is the circumference and r is the radius.

Front

What is the formula for the area of a rectangle?

Back

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

Front

If the circumference of a circle is 24π yd, what is the radius?

Back

The radius can be found using the formula: r = C/(2π). Here, r = 24π/(2π) = 12 yd.

Front

What is the formula for the volume of a cube?

Back

The volume of a cube is calculated using the formula: V = s³, where V is the volume and s is the length of a side.

Front

How do you find the height of a cone if you know the volume and radius?

Back

Rearranging the volume formula V = (1/3)πr²h gives h = 3V/(πr²).

Front

What is the area of a circle with a radius of 5 cm?

Back

Using the area formula A = πr², the area is A = π(5)² = 25π cm².

Front

What is the formula for the area of a triangle?

Back

The area of a triangle is calculated using the formula: A = (1/2)bh, where A is the area, b is the base, and h is the height.
