Answer:
87.5 ft^3
Step-by-step explanation:
Formula:
Volume = length x width x height.
Dimensions:
Length = 3 1/2 ft = 7/2 ft
Width = 5 ft
Height = 2 1/2 ft = 5/2 ft
Substitute and Find Volume:
Volume = (7/2 ft) x (5 ft) x (5/2) ft
Volume = 87.5 ft^3
If the diameter is 9 cm the radius is 4.5 cm (half the diameter). The area of a circle is given by the formula: 4πr^2, where π is the constant ratio of circumference to diameter (3.14159...).
3.14 cm x 4.5 cm = 14.13 cm^2. Remember, the units must be squared to represent area. 14.13 is extended to the nearest hundredth.
Whenever we divide a certain number by 10 or 100 or 1000... the decimal point of the number always moves to your left hand side.
for example: 25 or 25.00 is a number that has its decimal point after 5.
suppose we divide it by 10, the decimal point point moves as number of times as the number of zeros in the divisor. here, 10 has 1 zero. isn't it?
hence, decimal point moves 1 time or once to the left
2.500 or simply 2.5
on writing a percent as decimal..
we always have the divisor as 100.
number of zeros in 100 : 2
hence point moves 2 times or twice to the left.
25 / 100 = .25 or 0.25
on re-writing 0.25 as fraction, count the number of digits right to the point. it is 2 here.
hence there would be two zeros as well,i.e, 100
hence , 0.25 = 25/100
hope it helps you! :)
