If one circle has a diameter of 20 cm and a second circle has a diameter of 40 cm, what is the ratio of the area of the larger circle to the area of the smaller circle?

The ratio of the area of the larger circle to the area of the smaller circle will be: 4/1 or 4:1        

Step-by-step explanation:

The diameter of a larger circle = d = 40 cm

                                                 r = d/2 = 40/2 = 20 cm

The area of the larger circle = πr²

                                               = 3.14 (20)²

                                                = 3.14 × 400

                                                 = 1256 cm²

The diameter of a smaller circle = 20 cm

                                                   r = d/2 = 20/2 = 10 cm

The area of the smaller circle = πr²

                                                 = 3.14 (10)²

                                                 = 3.14 × 100

                                                 = 314 cm²

Thus,

The area of the larger circle = 1256 cm²

The area of the smaller circle = 314 cm²

Therefore,

The ratio of the area of the larger circle to the area of the smaller circle will be computed as:

reducing the ration into a simpler form

Thus, the ratio of the area of the larger circle to the area of the smaller circle will be: 4/1 or 4:1        

m∠cdf = 43° , m∠gdf = 114°, m∠gde = 23°, m∠edh = 23° , m∠cdh = 157°

step-by-step explanation:

since, it is given that de bisects the angle gdh ⇒ de divides the angle gdh into two equal angles.

⇒ m∠gde = m∠edh

⇒ 8·x   - 1 = 6·x + 5

⇒ x = 3

so, m∠gde = 8·x - 1 = 23°

and m∠edh = 23°

now, it is given ∠cde is an straight angle so, m∠cde = 180°

⇒ m∠cdf + m∠fdg + m∠gde = 180°

⇒ 43° + m∠fdg + 23° = 180°

⇒ m∠fdg = 114°

again, m∠cde = m∠cdh + m∠edh = 180°

m∠cdh + 23° = 180°

⇒ m∠cdh = 157°
