Question

Find the area under the curve y=4 x² from x=0 to x =5.​

Answer 1

Answer:

use integration to get the answer

Step-by-step explanation:

500/3 is the answer

Answer 2

Answer:

Here y = 4 – x2 can be written as x2 = 4 – y This curve is symmetrical about y-axis and does not lie beyond y = 4 when y > 4, where x2 is negative and x becomes imaginary. So the required area = area between the line y = 0 (x-axis) and y = 3 as shaded region
