What is the area bounded by y=x^2, x-axis, and lines x=0, x=7?
Curve y=x^2, x-axis और lines x=0, x=7 से घिरे region का area क्या है?
Show answer and explanation
Correct Answer
B. 343 / 3
ExplanationStep 1: area under a curve is ∫ y dx. Step 2: ∫_0^7 x^2 dx = 7^3/3 = 343/3. Step 3: exam note: when curve is above x-axis, area is direct integral.
Step 1: area under curve = ∫ y dx है। Step 2: ∫_0^7 x^2 dx = 7^3/3 = 343/3। Step 3: exam note: x-axis के ऊपर curve हो तो area direct integral होता है।
