What is the diameter of a circle whose area is quadrupled when the length of its radius is increased by 4cm?
The answer to your question is 8 cm diameter, increasing to 16 cm diameter: r2 squared = 4 x r1 squared and r2 = r1 + 4 r1 squared + 8r1 + 16 = 4r1 squared 3r1 squared - 8r1 - 16 = 0 Factors are (3r1 + 4)(r1 - 4), so original radius was 4cm (area 16pi) and increased radius is 8 cm (area 64pi).
What is the least number that when divided by 2 or 3 or 4 or 5 has a remainder of 1?
Well, for 2, it's 3. 3 divided by 2 is 1 r1 (r= remainder). For 3, 4. 4 divided by 3 is 1 r1 and so on and so fourth. Hope this helps!
