Answer:
h = 12 cm
Step-by-step explanation:
3053.63=πr^2h
Let r=9 and approximate pi as 3.14
3053.63=3.14 ( 9)^2 h
3053.63=3.14*81*h
3053.63=254.34h
Divide each side by254.34
3053.63/254.34=254.34h/254.34
12=h
Answer:
3 foot 3 inches
Step-by-step explanation:
How much deeper the hole should be = intended depth - current depth
Convert feet to inches for easy calculation
1 ft = 12 inch
5 x 12 = 60 inches
1 foot = 12
12 + 9 = 21 inches
60 - 21 = 39 inches
convert inches to feet
39 /12 = 3 feet 3 inches
