Question

solve question 14 and 15​

Answer 1

Answer:

Nothing ,I got my answer.

thanks for asking.

15.Area of the shaded region = area of the circle −area of the triangle ABC−area of the quadrant COD

Here, in triangle ABC ∠CAB=90⁰ (angle in a semicircle)

Hence triangle ABC is right-angled at A

Then applying Pythagoras theorem,

BC ²=AC²+AB²

BC ² =24²+7 ²

BC² =625

BC=25 cm

Therefore diameter of circle =25cm

i.e., Radius= 25/2

=12.5 cm

Then area of circle =πr ²

=490.625 cm²

Area of triangleABC= 1/2×base×height

=84 cm²

Area of quadrant = 1/4×πr ²

=122.65625 cm²

Therefore area of shaded region =490.625−84−122.65625=283.96875 cm ²

Answer 2

Kuch pta na ho to Bola bhi mt kro

Step-by-step explanation:

In physics, a force is any interaction that, when unopposed, will change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity.
