What is the area of the shaded region? Round to the nearest tenth.

The answer is 50.2cm²

Step-by-step explanation:

Area of the whole circle (the whole shape)

A= πr²

A= 3.14 x (5cm)²

A= 3.14 x 25cm

A= 78.5cm²

Area of the part in the middle (non-shaded part)

A= πr²

A= 3.14 x (3cm)²

A= 3.14 x 9cm

A= 28.26cm²

78.5cm² - 28.26cm² = 50.24cm²

Answer rounded to the nearest tenth: 50.2cm²

Hope this helps :)

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

answer:

125 yards

explanation:

75+50=125. that is my answer
