Answer:
volume of the hemisphere ≈1577.5 cm³
Step-by-step explanation:
To find the formula for calculating the volume of a hemisphere, we will follow the steps below:
write the formula for calculating the volume of a hemisphere.
volume of a hemisphere = volume of a sphere ÷2
= πr³ ÷ 2
= πr³
WHERE r is the radius
from the question given, radius= 9.2 cm
π is a constant and is ≈ 3.14
we can now proceed to insert the values into the equation
volume of a hemisphere = πr³
= × 3.14 ×9.2³
= × 3.14 ×753.571
≈1577.5 cm³ to the nearest tenth of cubic centimeter
volume of the hemisphere ≈1577.5 cm³
Answer:
870
Step-by-step explanation:
Assuming you mean
30
Using the definition
n =
where n! = n(n - 1)(n - 2) ..... 3 × 2 × 1
Then
30 =
=
Cancel the terms 28(27)... on numerator/ denominator, leaving
30 = 30 × 29 = 870
