Uca is designing a propeller system that consists of 3 blades, each of which is

zmey [24]

Answer:

The weight of the three blades together is $134\ g$

Step-by-step explanation:

step 1

Find the area of the circle

The area of the circle is equal to

$A=\pi r^{2}$

we have

$r=4\ in$

assume

$\pi=3.14$

substitute

$A=(3.14)(4)^{2}$

$A=50.24\ in^{2}$

step 2

Find the area of the 3 blades

we know that

The area of the 3 blades represent a central angle of 60 degrees, so

its a 1/6 of the area of complete circle

$A=50.24/6=8.37\ in^{2}$

step 3

Find the weight of the three blades together to the nearest gram

$(8.37\ in^{2})*(16\ g/in^{2})=134\ g$

Romashka [77]

Answer:

The value of x is 14.

Step-by-step explanation:

We know that:

ΔABC ≅ ΔEFG
21 x 2/3 = x

Work:

21 x 2/3 = x
=> 7 x 3 x 2/3 = x
=> 7 x 2 = x
=> 14 = x

Hence, the value of x is 14.
