Answer:
The ratio of the radius of the smaller watch face to the radius of the larger watch face is 4:5.
Step-by-step explanation:
Let the Area of smaller watch face be 
Also Let the Area of Larger watch face be 
Also Let the radius of smaller watch face be 
Also Let the radius of Larger watch face be 
Now given:

We need to find the ratio of the radius of the smaller watch face to the radius of the larger watch face.
Solution:
Since the watch face is in circular form.
Then we can say that;
Area of the circle is equal 'π' times square of the radius 'r'.
framing in equation form we get;


So we get;

Substituting the value we get;

Now 'π' from numerator and denominator gets cancelled.

Now Taking square roots on both side we get;

Hence the ratio of the radius of the smaller watch face to the radius of the larger watch face is 4:5.
Answer:
231
Step-by-step explanation:
first of all it must be a cuboid bcoz a cube's edge is same i.e length =breadth= height.
now volume of cuboid =lbh
11/2×21/2×4
=231
ans....
Answer:
2,744 feet³
Step-by-step explanation:
Volume = Length * Width* Hight
A cube has all the sides equal in measure so Length and Width and Hight are equal and are given in the picture to be 14 feet.
V = 14 *14*14 = 2,744 cubic feet
