A chickpea is approximately spherical. Chickpeas have a diameter of about 9 millimeters. Estimate the volume of a chickpea. Round your answer to the nearest tenth of a cubic millimeter.
the answer is 381.7mm^3
To estimate the volume of a chickpea, we can use the formula for the volume of a sphere:
V = (4/3)πr³
where V is the volume and r is the radius of the sphere.
Given that the diameter of the chickpea is about 9 millimeters, we can find the radius by dividing the diameter by 2:
r = 9 mm / 2 = 4.5 mm
Now we can plug this value into the volume formula:
V = (4/3)π(4.5 mm)³
Using the value of π ≈ 3.14159, we can calculate the approximate volume:
V ≈ (4/3)(3.14159)(4.5 mm)³
V ≈ 381.7037 mm³
Rounding to the nearest tenth of a cubic millimeter, the estimated volume of a chickpea is approximately 381.7 mm³.
Volume = 4/3 π r^3
d/2 = r
I'll let you do the calculations.
