Answer:
22
Step-by-step explanation:
Answer:
131.95 cm
Step-by-step explanation:
The Formula for the circumference of a circle is πd where d is the diameter. Therefore you simply multiply 42 with PI to get the circumference
You can use the Pythagorean Theorem to find the length of the third side AB (Identified as "x" in the figure attached in the problem), which says that in a right angled triangle, the square of the hypotenuse is equal to the sum of the squares of the legs:
a² = b²+c²
As we can see the figure, the triangle does not have an angle of 90°, but it can be divided into two equal parts, leaving two triangles with a right angle. We already have the values of the hypotenuse and a leg in triangle "A" , so we can find the value of the other leg:
b = √(a²-c²) b = √(10²-4²) b = 9.16
With these values, we can find the hypotenuse in the triangle "B": x = √b²+c² x = √(9.16)²+(4)² x = 10
Firstly we need to find an area of a single tile:
6 * 14 = 84 square inches
Now we just need to find out how many tiles of 84 square inches will fit in an area of 8900 square inches:
8900 ÷ 84 = 105,952380952381
Assuming we can't cut a tile into pieces, we may round the result to 106.
Answer: The least number of tiles Jared will need is <u>106</u>.
