Answer:
Step-by-step explanation:
1). Since, XM is the radius of the circle,
Therefore, area of the circle =
=
=
= 452.39 units²
2). Circumference of a circle = 2πr
= 2π(XM)
= 2π(12)
= 24π
= 75.40 units
3). By applying Pythagoras theorem in ΔYXM,
YM² = XY² + XM²
(43)²= (XY)² + (12)²
1849 - 144 = (XY)²
XY = 41.29 units
4). tan(∠M) =
=
m∠M =
= 73.79°
5). Area of ΔXYM =
=
= 247.74 square units
6). Area of the minor sector created by ΔXYM =
=
= 92.73 units²

Answer:
The area of the clock
Step-by-step explanation:
We have been given the face of the clock that is
So that is also the circumference of the clock.
Since the clock is circular in shape.
So
From here we will calculate the value of radius of the clock that is circular in shape.
Then
Now to find the area of the clock we will put this value of (r) in the equation of area of the circle.
Now
So the area of the face of the clock =
