Find the volume of each sphere or hemisphere. Round to the nearest tenth.

1 answer:

6 0

We know that
volume of a sphere=(4/3)*pi*r³

in this problem
circumference=26 m
circumference=2*pi*r
so
26=2*pi*r----------> r=26/(2*pi)----> 4.14 m

volume of a sphere=(4/3)*pi*(4.14)³---> 297.08 m³------> 297.1 m³

the answer is
volume of a sphere is equal to 297.10 m³

Answer:

0.0001042

Step-by-step explanation:

Power of tens rule states that if the denominator of a fraction has the positive power of 10, decimal in the numerator will be shifted to the left by the same number of places as exponent.

10⁴) 1.042 = $\frac{1.042}{10^4}$
