Answer:
The ladder will reach 5.6 meters high.
Step-by-step explanation:
The tree, the ground and Kali's ladder form a triangle whose hypotenuse is the ladder, base
the ground, and perpendicular
the tree. Thus from Pythagorean theorem:
Since and
Thus the ladder will reach 5.6 meters high.
Step-by-step explanation:
Given , The length of side of the square is 8 feet.
Since a circle is inscribed in the square. Then the diameter of the circle is equal to the length of side of the square .
Therefore the diameter of the circle is = 8 feet.
Radius of the circle is(r) = feet = 4 feet
The area of the circle is= 3.14 r²
= 3.14 × 4² square feet
= 50.24 square feet
The area of the square is = side × side
= 8×6 square feet
=64 square feet
Therefore the area of remaining board = (64- 50.24)square feet
=13.76 square feet
