So. 2/5 of the fish are surgeon fish. Meaning that 40% of the fish are surgeonfish. From that 40%, the 75% are yellow tangs. So the 75% of that 40% equals to 30% of all fish (since (3/4)*(2/5)=3/10)

So the aquarium has 30% OR 3/10 of its fish being yellow tangs

The cylinder shown has a lateral surface area of about 400 square inches. Which answer is closest to the measure of the cylinder

myrzilka [38]

Answer:

r = 1.59inch

the radius of the cylinder is

1.59inch

Step by step Explanation

lateral surface of a cylinder can be calculated using the below formula

Surface Area= 2 πr h

We were given area as 400inch^2 and height as 40inch then substitute we have

400 = 2 ×π × r ×40

400= 2×22/7×40

Then do the calculation, where, π

=22/7

400 = r × 251.2

Make r subject of formula we have

r = 400 / 251.2

r = 1.59inch

Therefore, the radius of the cylinder is

1.59inch
