Surface area is the sum of the areas of all faces (or surfaces) on a 3D shape. A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces.

Considered as it only taking the area of flat surfaces of a 3D object, no

Find the area of the curve y= f(x) = x between x = 5 and x = 10

Tems11 [23]

Answer:

the area of the curve y= f(x) = x between x = 5 and x = 10

$A=\frac{75}{2}$

Step-by-step explanation:

Finding the area of the curve y = f(x) = x between x = 5 and x = 10

Using the Area formula

$A=\int _a^b\:f\left(x\right)dx$

As the area of curve lies between x = 5 and x = 10

a = 5, b = 10

so the integral expression becomes

$A=\int _5^{10}xdx$

$\mathrm{Apply\:the\:Power\:Rule}:\quad \int x^adx=\frac{x^{a+1}}{a+1},\:\quad \:a\ne -1$

$A=\left[\frac{x^{1+1}}{1+1}\right]^{10}_5$

$=\left[\frac{x^2}{2}\right]^{10}_5$

$=\frac{1}{2}\left[10^2-5^2\right]$

$=\frac{1}{2}\cdot \:75$

$=\frac{75}{2}$

Therefore, area of the curve y= f(x) = x between x = 5 and x = 10

$A=\frac{75}{2}$
