integral from-7 to 0 of (4+sqrt(49-x^2))

\int_{- 7}^{0} (4 + 49 - x^{2}) d x

28 + \frac{49 π}{4}

Decimal

66.48451 \dots

Solution steps

\int_{- 7}^{0} 4 + 49 - x^{2} d x

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int_{- 7}^{0} 4 d x + \int_{- 7}^{0} 49 - x^{2} d x

\int_{- 7}^{0} 4 d x = 28

\int_{- 7}^{0} 49 - x^{2} d x = \frac{49 π}{4}

= 28 + \frac{49 π}{4}
