Q. A cylinder has a base radius of 5cm and a height of 16cm. What is its volume in cubic cm, to the nearest tenths place?
Formula Explanation: The formula to calculate the volume of a cylinder is V=πr2h, where r is the radius of the base and h is the height of the cylinder.
Substitution Step: Substitute the given values into the formula: r=5cm and h=16cm. V=π(5cm)2(16cm)
Volume Calculation: Calculate the volume using the substituted values:V=π(25cm2)(16cm)V=π(400cm3)
Pi Calculation: Use the value of π (approximately 3.14159) to calculate the volume: V≈3.14159×400cm3V≈1256.636cm3
Rounding Step: Round the volume to the nearest tenth:V≈1256.6cm3
