Find the length of the third side of triangle if its midline measures 45cm​

20 cm is the length of third side of triangle

Step-by-step explanation:

Length of 1st side = a

Length of 2nd side = 10cm = b

Length of 3rd side = 15cm = c

So,

Perimeter of triangle = 45 cm

a+b+c = 45cm

a + 10 + 15 = 45 cm

.'. a = 45-25 cm

= 20 cm

answer:      

step-by-step explanation:

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
