Answer:

541.1 square feet

Step-by-step explanation:

A = πr²

1) convert in. to ft because answer is in sq. ft

78 in => 6.5 ft

2) Find radius of entire area

6.5 ft + radius of inner circle

6.5 + 10 = 16.5

3) Calculate area of combined circles

A = π(16.5)²

A = 855.3 sq. ft

4) Find area of inner circle

A = π(10)²

A = 314.2 sq. ft

5) Subtract area of inner circle from combined area

855.3 sq ft - 314.2 sq. ft =<u> 541.1 sq. ft</u>
