Answer:

Make it a new number between 1 and 10

Move the decimal point to make 31830000.0 a new number between 1 and 10. Because our number is greater than 10, we move the decimal point to the left. Drop any trailing zeroes. Keep track of how many times we move the decimal point.

31830000.0 -> 3.183Because our original number was greater than 10, the power of 10 is positive. Remember, we moved the decimal point 7 times, so the exponent is positive 7:

7 over 10

                                   

4. Final result 3.183.7 over 10

Our new number is 3.183. We moved the decimal point 7 times.

A cone with diameter 20 cm and a height of 20 cm. Find the volume of the cone rounded to the nearest tenth.
zhuklara [117]

Answer:

2094.4 cm³

Step-by-step explanation:

The volume of a cone =πr²h/3

Where

r = radius = Diameter/2

Diameter = 20cm, radius = 20cm/2 = 10cm

Height = 20cm

Volume of a cone = π × 10² × 20/3

Volume of a cone = 2094.3951 cm³

Approximately to the nearest tenth = 2094.4 cm³

Therefore , the volume of a cone = 2094.4 cm³
