Question

The curved part of this figure is a semicircle.

What is the best approximation for the area of this figure?

Answer 1

Answer:

0 because it starts from middle from horizontal to vertical, its my openion

Answer 2

The approximate area of the given figure is 94.18 which is equal to 94.2

• The given figure can be split as the triangle and a semi-circle.
• The total area will be the sum of area of the triangle and semi-circle.
• The height of the triangle is 4 units and its base is 9 units.So the area of the triangle is 18 units.
• The diameter of the semicircle is the hypotenuse of the right angled triangle which is equal to 91^1/2.Which makes the area of the semicircle as 76.18 units
• So the total area becomes 94.18 units
