A DVD has a diameter of 26 centimeters. What is the area of the DVD? Round your answer to the nearest hundredth. Use 3.14 for π.

Alinara [238K]

Answer:

A =530.66 cm^2

Step-by-step explanation:

A DVD is a circle so we can use the formula for area of a circle

A = pi r^2

We can find the radius from

r = d/2 where d is the diameter

r = 26/2

r = 13

A = pi *13^2

A = pi *169

Substituting in for pi

A = (3.14) * 169

A =530.66

Six equilateral triangles are connected to create a regular hexagon. The area of the hexagon is 24a^2 – 18 square units. Which i

netineya [11]

we know that

The area of the hexagon is equal to the sum of the areas of the six equilateral triangles

Let

x-------> area of one equilateral triangle

$6x=24a^{2} -18$

Divide by $6$ both sides

$x=4a^{2} -3$ -------> area of one equilateral triangle

To find an equivalent expression for the area of the hexagon based on the area of a triangle, multiply the area of one equilateral triangle by $6$

$6*(4a^{2} -3)$

therefore

the answer is

The equivalent expression is equal to $6*(4a^{2} -3)$
