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>
0.98 ,0.34 , 0.27
Pretend the zeros or decimals ain't there. It's still the same thing . After solving remember to add the decimal or zeros back in for your final answer .
