What is the surface area of this cylinder? Use a ~ 3.14 and round your answer to the nearest hundredth.
7 mm
9 mm
square millimeters

Surface are of cylinder having height 9 mm and radius 7 mm is 703.36 mm²

Step-by-step explanation:

We are given:

Height of cylinder = 9 mm

Radius of cylinder =  7 mm

We need to find surface area of cylinder.

The formula used to find surface area of cylinder is:

Now, putting values and finding surface area of cylinder

So, surface are of cylinder having height 9 mm and radius 7 mm is 703.36 mm²

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.

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
