Answer:

The approximate value of the area is 153.86\ m^{2}

Step-by-step explanation:

we know that

The area of the circle (landing pad) is equal to

A=\pi r^{2}

we have

r=7\ m

substitute

A=\pi (7)^{2}

A=49\pi\ m^{2} ----> exact value of the area

Find the approximate value

assume \pi=3.14

A=49(3.14)=153.86\ m^{2} ------> approximate value of the area

Answer:

Area of Circular landing pad = 307.72 m^2

Step-by-step explanation:

Area of Circular landing pad = 2πr^2

where r = radius of circular landing pad = 7m

π = 22/7 = 3.14

by placing all these value in the formula

Area of Circular landing pad = 2*3.14*(7^2)

Area of Circular landing pad = 6.28*49

Area of Circular landing pad = 307.72 m^2

Virty [35]

Answer:

A) 220.5 mm^2

Step-by-step explanation:

<u>Explanation</u>:-

Given A regular triangular pyramid has a base of area is 31.5mm^2

and also given surface area of triangular pyramid is 252 mm ^2

by using formula

surface area of  regular triangular pyramid = base of area + half of lateral surface.

surface area = area of the pyramid X \frac{1}{2} lateral surface

252 = 31.5 + \frac{1}{2} lateral surface

252-31.5= \frac{1}{2} lateral surface

220.5 = lateral area of triangular pyramid

lateral area of triangular pyramid = 220.5 mm^2

Quinn is flying a kite. The angle of elevation formed by the kite string and the ground is 40°, and the kite string forms a stra
emmasim [6.3K]

The distance between the ground and the kite to the nearest foot is 64 ft.

<h3>What is a right angle triangle?</h3>

A right angle triangle is a triangle that has one of its sides as 90 degrees. The situation forms a right angle triangle.

Hence,

The length of the kite string is the hypotenuse side of the triangle formed.

The height between the ground and the kite is the opposite side of the triangle formed.

Therefore, using trigonometric ratio,

sin 40 = opposite / hypotenuse

sin 40 = h / 100

cross multiply

h = 100 sin 40

h = 100 × 0.64278760968

h = 64.2787609687

h = 64 ft

Therefore, the distance between the ground and the kite to the nearest foot is 64 ft.

How is this answer D?
kompoz [17]
It's a equilateral triangle with each side being equal to the radius.

So the area is \dfrac{8^2\sqrt 3}{4}=\dfrac{64\sqrt3}{4}=16\sqrt3
