Q. What is the volume, in cubic cm, of a cylinder with a height of 18cm and a base radius of 9cm, to the nearest tenths place?Answer: V=□cm3
Volume Formula: To find the volume of a cylinder, we use the formula V=πr2h, where V is the volume, r is the radius of the base, and h is the height of the cylinder.
Square Radius Calculation: First, we need to square the radius of the base. The radius is 9cm, so squaring it gives us 92=81cm2.
Multiply by Height: Next, we multiply the squared radius by the height of the cylinder. The height is 18cm, so we calculate 81cm2×18cm=1458cm3.
Multiply by Pi: Now, we need to multiply this result by π (pi), which is approximately 3.14159. So, we calculate 1458cm3×π≈1458cm3×3.14159.
Final Calculation: Performing the multiplication gives us approximately 4582.0742cm3.
Round to Nearest Tenth: Finally, we round the result to the nearest tenth place, which gives us 4582.1cm3.
