A cone with radius 5cm and height 12 cm

Step-by-step explanation:

314.16cm^3

This is because Volume is equal to:

V=πr^2*h /3

where

π=3.14, r=5, h=12

lets calculate

V=3.14*25*12/3=314cm^3

answer: a rhombus has two lines of symmetry that run through one vertex to the one directly across it. unlike a square, planes through the center of each edge of a rhombus do not yield mirrored sides.

step-by-step explanation:

answer: 1722

step-by-step explanation:

given: the mass of saturn=

the mass of mercury=

the number of times the mass of saturn is greater than the mass of mercury

hence, the mass of saturn is 1722 times greater than the mass of mercury.
