Answer:
4) 201.06 yd²
5) 39 ft²
6) 25 in²
7) 24 in²
8) 4 yd²
9) (di po clear yung pic) if r=1, then A= 3.14ft². If r=3, then A=28.27 ft²
Step-by-step explanation:
4)
r= 8yd.
A = πr²
A ≈ 201.06yd²
5)
b=13ft., h=6ft
A = b•h/2
A = (13)(6)/2
A = 39 ft²
6)
s=5 in.
A=s²
A= 25in²
7)
l=12 in, w=2 in
A= l × w
A= 12×2
A=24 in²
8)
s= 2yd
A= s²
A= 2²
A=4yd²
9)
r=1ft
A=πr²
A = 3.14ft²
or
r=3ft
A=πr²
A= 28.27 ft²
(pili nalang po kayo ng r sa number 9, di po kasi clear yung pic sakin kung 1 or 3 po yung radius, thank you po)
