The diameter of a cylindrical water tank is 10ft, and its height is 9ft. What is the volume of the tank? Use the value 3.14 for π, and round your answer to the nearest whole number. Be sure to include the correct unit in your answer. PLZ answer ASAP PLZ

785

Step-by-step explanation:

because 3.14 times 5 (radious) squared(25) times ten is 785

c. 16 units

step-by-step explanation:

mark brainliest and have a great day!

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
