A cylinder is 20 inches long and has a diameter of 10 inches. The approximate volume of the cylinder is blank cubic centimeters. 1,570

200

630

6,280

Step-by-step explanation:

V= π r^2h

^

Pi

First you need the radius, if the diameter is 10inches divide by 2 = 5 inches, that's your radius.

π(5inches)^2 times (20 inches)

firsr work out 5^2= 5x5= 25

π(25inches) times (20inches)

25x20=500π inches

500π =1,570.7963267948966192313216916397514420985

which rounds to 1,570, the first one is your answer

the answer is somewhere there guys it really . there im just not gonna answer

step-by-step explanation:

but i'm guessing ur first option tho

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
