PLEASE HELPP! a cylinder has the volume of 1000 pi show with working that if the height = 20cm then the radius = 5 cm.

Aline has a slope of 1/4 and passes through point (0.4,-1/2). what is the value of the y-intercept?

Solve by any method (graphing, substitution or linear combination)y = x - 82x + 3y = 1a) (2, -6)b) (5, -3)c) (4, -4)d) (0, -8)i figured it out. the answer is (5, -3)

What is the greater volume 72 quarts or 23 gallons
