The shaded area is the area of the rectangle minus the area of the hemisphere.

A=(6*3)-(π3^2)/2

A=18-9π/2

A=18-4.5π, and if we approximate π≈3.14

A=18-4.5(3.14)

A=18-14.13

A=3.87 cm^2

In isoceles triangle the length of a leg is 17cm, and the base is 16cm. Find the length of the altitude to the base
Elan Coil [88]

This triangle has base 16 therefore the sides must be 17cm and 17 cm

When we make a altitude it divides it into two right triangles and there is a property in which the altitude of the isoceles triangle divides the base in 2 equal halves

So the side of the right triangle will be x , 8 , 17

Using pythgoreus theorem

x²+8²=17²

x = √225

x = 15

So the altitude is 15 cm
