The perimeter of a kite is 50 mm. The length of one of its sides is 1 mm more than twice the length of another. Find the length
rosijanka [135]

Answer:

The length of the longest side is 13mm

Step-by-step explanation:

Represent the two sides with a and b, where a is the longest

Perimeter = 50

a=b + 1

Required

Determine the length of the longest side

Perimeter of a kite is calculated as thus:

Perimeter = 2(a + b)

Make b the subject in a=b + 1

b = a -1

Substitute a - 1 for b and 50 for Perimeter in Perimeter = 2(a + b)

50 = 2(a + a - 1)

Divide through by 2

25 = a + a - 1

25 = 2a- 1

Add 1 to both sides

25 + 1 = 2a - 1 +1

25 + 1 = 2a

26 = 2a

Solve for a

a = 26/2

a = 13

<em>Hence, the length of the longest side is 13mm</em>

Whats the area of a quarter-circle with diameter of 4 meters
kkurt [141]
The answer is 3.14 m

The area (A) of the circle with radius r is: A = π · r²
The area of the quarter of the circle is: A1 = 1/4A = 1/4 · π · r²

We have:
A1 = ?
r = ?
π = 3.14
d = 4 m

A diameter d is the twice of the radius r: d = 2r.
Therefore, the radius is the half of the diameter: r = d/2
So, the area of the quarter circle would be:
A1 = 1/4 · π · r² = 1/4 · π · (d/2)² =1/4 · π · d²/2² = 1/4 · π · d²/4 = 1/16 · π · d²

A1 = 1/16 · π · d² = 1/16 · 3.14 · 4² = 1/16 · 3.14 · 16 = 3.14 m
