If a pool is 4 m wide and 16 m diagonally across, how long is the pool? (Pyth. Theorem)

alukav5142 [94]

Answer:

$L=4\sqrt{15}\ m$

or

$L=15.49\ m$

Step-by-step explanation:

we know that

Applying the Pythagorean Theorem in the rectangular pool

$d^2=L^2+W^2$

where

d is the diagonal of the pool

L is the length of the pool

W is the wide of the pool

we have

$d=16\ m\\W=4\ m$

substitute the given values

$16^2=L^2+4^2$

solve for L

$L^2=16^2-4^2\\L^2=240\\L=\sqrt{240}\ m$

simplify

$L=4\sqrt{15}\ m$

or

$L=15.49\ m$

From a rectangular metal sheet whose measure 30cm×20cm, a circular portion whose radius is 10.5cm is cut off .Find the area of r

miskamm [114]

Answer:

254 cm²

Step-by-step explanation:

Calculate first the total area

A = 30*20 = 600 cm²

Then calculate the area of the cercle

A= 10.5²*π = 346.36≈346 cm²

Then substract the area of the circle from the total one:

600-346= 254 cm²
