Find the area of the shaded region. Round your answer to the nearest tenth if needed.<br><br> 2B
SCORPION-xisa [38]

Answer:

The area of the park is calculated through the equation,

A = 0.5ab(cos C)

Substituting the given above,

A = 0.5(533 ft)(525 ft)(cos 53°)

A = 84201.44 ft²

2. We find the radius of the second figure by the equation,

r = C / 2π

Substituting,

r = (30 in) / (2π) = 4.77 in

The radius of the first one is 9 inches. Getting the difference of these two figures will give us an answer of 4.225 inches.

Diameter of the basketball rim = 18 inches

Circumference of the basketball = 30 inches

You would have to fin the area so= pi*r^2

Basketball rim = 3.14 * (18/2)^2 = 3.14 * 9^2 = 3.14 * 81 = 254.34 in^2

The find the Circumference so= 2*pi*r

30 = 2*3.14*r

r = 30 / (2*3.14) = 30 / 6.28 = 4.78 inches

basketball = 3.14 * (4.78)^2 = 3.14 * 22.85 = 71.75 in^2

254.34 - 71.75 = 182.59 in^
