Answer:
50.24
Step-by-step explanation:
r = d/2
r = 8/2
r = 4
Area of a Circle:
A = πr²
Work:
A = πr²
A = 3.14(4²)
A = 3.14(16)
A = 50.24
In order for us to help you, you need to ask a question that deals with going under math section or a different subject.
Try this:
1) area of f-yard is 60*70=4200 feet²;
2) area of b-yard is 10*30=300 feet², according to condition '<span>on half of his back yard' this area should be 0.5*300=150 feet</span>².
3) total: 4200+150=4350 feet².
<span>250*(2*60)=30000
125*(3*60)=22500
22500+30000=52500
52500:((3+2)*60)=175 (</span><span>words per minute)</span>
