The capacity of a cylindrical water tank is 539 litres. If its height is 1.4 meter then find the radius of the base.

natulia [17]

Answer:

350m

Step-by-step explanation:

capacity= volume/1000
but we know that volume of cylinder is πr²h so substitute it I'm the volume space
then substitute for π as 22/7, h as 1.4 , and also capacity as 539
539= ((22/7)×r²×1.4)/1000
when you simplify you get r as 350m

Mary crocheted a rectangular blanket whose diagonal measures approximately 7.21 feet. What are the most likely length and width

mote1985 [20]

Answer:

If both sides are integers, one side will be 4 feet and the other will be 6 feet. The other solution is the symmetrical solution (4 feet instead of 6 feet, and 6 feet instead of 4 feet).

Step-by-step explanation:

We have a rectangular blanket, that has a diagonal that measures h=7.21 feet.

The two sides of the rectangle a and b can be related to the diagonal h by the Pithagorean theorem:

$a^2+b^2=h^2$
