# What is the perimeter of a parallogram if the length is 17 cm and the width is 30cm?

parallelogram has two pairs of equivalent sides therefore it would be 17+17+30+30=94cm

### What is the perimeter of a rectangle with length of 11 cm and with of 4 cm?

To calculate the perimeter of a rectangle, you need to add together the length of each side of the rectangle. For a rectangle that is 11cm x 4cm, you would add these numbers together, then multiply it by 2 (this is because there are two sides that are 11cm and two sides that are 4cm). Thus: (11+4) x 2 = 30cm.

### How do you calculate the volume of a testicle?

Measure the length, depth and width with a ruler, a pair of calipers (or ultrasound imaging, if you have a spare machine lying around). Calculate the volume using the formula for the volume of an ellipsoid: 4/3 π × (length/2) × (width/2) × (depth/2). (That's 1.3 times Pi, times half the length, times half the width, times half the depth.) In healthy European adult human males, average testicular volume is 18cm³ (1.09 in³) per testis…
