Calculate the difference in the lung volumes of a male athlete who is 62 inches tall and a female athlete who is 56 inches tall Show your work?

Male athlete: 62 x 2.54 = 157.48 cm 157.48 cm x 29 cm^2 = 4,566.92 cm^3 Female athlete: 56 x 2.54 = 142.24 cm 142.24 cm x 22 cm^2 = 3,129.28 cm^3 Difference: 1,437.64


How big is 30 cm?

How big is a 3 cm cyst?

A 3 cm cyst is roughly the size of a large marble or a small grape. To visualize it, a 3 cm diameter means it has a radius of 1.5 cm, so it can fit comfortably in the palm of your hand. While it's not excessively large, its significance depends on its location and the context of any symptoms it may cause.


The small cylinder can fill the bi cylinder up to 5 cm. the small cylinder has a height of 12 cm and radius of 3 cm. work out the radius of the big cylinder?

To find the radius of the big cylinder, we first calculate the volume of the small cylinder using the formula ( V = \pi r^2 h ). Given the small cylinder has a height of 12 cm and a radius of 3 cm, its volume is ( V = \pi (3^2)(12) = 108\pi ) cm³. Since the small cylinder can fill the big cylinder up to 5 cm in height, the volume of the big cylinder for that height is ( V = \pi R^2 (5) ), where ( R ) is the radius of the big cylinder. Setting the volumes equal gives ( 108\pi = \pi R^2 (5) ), which simplifies to ( R^2 = \frac{108}{5} ) and ( R = \sqrt{\frac{108}{5}} \approx 4.67 ) cm.
