Here is a cuboid,

Dmitry_Shevchenko [17]

Length = 80

Breadth = 30

Height = 30

Total surface area of a cuboid is=

2 ( lb + bh + hl )

Putting the values in the formula,

We get,

= 2 [ (80 x 30) + (30 x 30) + (30 x 80)]

= 2 (2400 + 900 + 2400)

= 8100 cm²

THANK YOU!!

A = 1 4 π d 2 what is the formula to calculate the diameter of a circle

Anestetic [448]

Answer:

$D=2\sqrt{\frac{A}{\pi}}$

Step-by-step explanation:

we know that

The area of the circle is equal to

$A=\frac{1}{4}\pi D^{2}$

where

D is the diameter of the circle

Solve for D

That means-----> Isolate the variable D

Multiply both sides by 4 to remove the fraction

$4A=\pi D^{2}$

Divide both sides by π

$\frac{4A}{\pi}=D^2$

square root both sides

$\sqrt{\frac{4A}{\pi}}=D$

Rewrite

$D=\sqrt{\frac{4A}{\pi}}$

Simplify

$D=2\sqrt{\frac{A}{\pi}}$
