Try and convert mega liters to liters by multiplying it by a million and then make an equation or a proportion
Math - Please help
Omg I hate clowns haha. So the area of a circle is A=pi(r^2), and you know that the area of the circle is 2,123 square feet, right? So just set them equal as 2,123=pi(r^2), and solve for r, or the radius. Just divide both sides by pi and then square root both sides. Now that y...

If i remember you just take two out of the three and solve using elimination. Then plug in your found variables to the third equation and youll have your variables! Its a lot of work per problem though

4, for the first one seems iffy. You might wanna use a comma after book. =This is the book, the cover of which is red. If you get so desperate just type your sentences in to microsoft word and spell check
geometry
Find the volume of the smaller one by using a proportion. The volume is 150, and then just divide it by 3. Pretty simple once you get it, and your answer would be 50 sec.
math
Use the equation vertex=-b/2a. b would be 12 a would be -2 That gets you the x value of the vertex, which is 3. Plug in 3 for x now to get y. y=-2(3)^2+12(3)-13 y=36+36-13 y=59. Your vertex is (3,59).
