Question

Awnser for 90 points first one gets it so

Answer 1

Shaded region is 505.54 m².

-------------------------

Radius of inner circle:

• r = 16/2 = 8 m

Area of inner circle:

• A = πr² = 3.14*8² = 200.96 m²

Radius of outer circle:

• r = 8 + 7 = 15 m

Area of full circle:

• A = 3.14*15² = 706.5 m²

Shaded region the difference of the areas of circles:

• A = 706.5 - 200.96 = 505.54 m²
