A circle with radius \pink{6}6start color #ff00af, 6, end color #ff00af has a sector with a central angle of \purple{48^\circ}48

alexandr1967 [171]

Answer:

Therefore,

The area of the sector is 15.09 unit².

Step-by-step explanation:

Given:

Circle with,

radius = r = 6 unit

central angle = θ = 48°

pi = 3.143

To Find:

Area of sector = ?

Solution:

If 'θ' is in degree the area of sector is given as

$\textrm{Area of Sector}=\dfrac{\theta}{360}\times \pi r^{2}$

Substituting the values we get

$\textrm{Area of Sector}=\dfrac{48}{360}\times 3.143\times 6^{2}$

$\textrm{Area of Sector}=15.0864=15.09\ unit^{2}$ rounded to nearest hundredth

Therefore,

The area of the sector is 15.09 unit².

C. 9 square roots of 2

To answer this question, it's super important that you understand the ratio of sides for special triangles. This triangle in particular, a 45-45-90 triangle, has a ratio between the legs and hypotenuse of 1:1:

Since we are given the value of the hypotenuse, we know that the value of the two sides multiplied by $\sqrt{2}$ will be 18. Knowing this, we can write out an equation:
