A dinner table is a perfect circle with a diameter of 8 feet. With dinner plates that each a diameter of exactly 1 foot, how muc
Harlamova29_29 [7]

The area of the tablecloth showing is approximately 45.55 square feet

<h3>What is an area?</h3>

The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the circle in a two-dimensional plane is called as the area of the circle.

It is given that:-

The diameter of the dinner table, D = 8 feet

The diameter of each plate, d = 1 feet

The number of people at the dinner table = 6 people

The number of plates = 6 plates

The area of the table cloth, A₁ = π·D²/4

∴ A₁ = π × 8²/4

The area covered by the 6 plates, A₂ = 6·π·d²/4

A₂ = 6 × π × 1²/4

Let 'A' represent the area of the tablecloth showing when the table is set for six people, we have;

A = A₁ - A₂

∴ A = π × 8²/4 - 6 × π × 1²/4 ≈ 45.55 ft.²

Therefore the area of the tablecloth showing when the table is set for six people, A ≈ 45.55 ft.²

Help please explain ​
MatroZZZ [7]

Given:

\sin^{-1}\left(\dfrac{5}{8}\right)=A

To find:

The correct equivalent equation.

Solution:

We have,

\sin^{-1}\left(\dfrac{5}{8}\right)=A

Taking sin on both sides, we get

\sin \sin^{-1}\left(\dfrac{5}{8}\right)=\sin A

\dfrac{5}{8}=\sin A                      [\because \sin (\sin^{-1}\theta )=\theta]

Interchanging the sides, we get

\sin A=\dfrac{5}{8}

Therefore, the correct option is 4.
