When you estimate you either round up or down to get an even number. It's easier to mentally multiply numbers ending in 0.
Answer:
3,761.46 m³
Step-by-step explanation:
Volume of a cone = 1/3πr²h
π = 3.14
radius, r = diameter/2
= 25/2 = 12.5 m
Height, h = 23m
Volume of a cone = 1/3πr²h
= 1/3 * 3.14 * 12.5² * 23
= 1/3 * 3.14 * 156.25 * 23
= 11,284.375 / 3
= 3761.4583333333
Approximately,
Volume of the cone = 3,761.46 m³

Answer:
y + (x-4)
Step-by-step explanation:
4 less than x= x-4
y exceeds 4 less than x = y + (x-4)
Answer:
r ≈ 6
Step-by-step explanation:
r= <u>414.78</u>
π x 11
≈ 5.99848
Because of this, the answer is rounded up to 6, but the exact answer is about 5.99848
