The equation of a circle is given by (x + 3.5) ^ 2 + (y - 2.82) ^ 2 = 25 What is the area of a 52 degrees sector of this circle?
Sunny_sXe [5.5K]

Answer:

≈ 11.34 units²

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

(x + 3.5)² + (y - 2.82)² = 25 ← is in standard form

with r² = 25 ⇒ r = \sqrt{25} = 5

The area (A) of the sector is calculated as

A = area of circle × fraction of circle

   = πr² × \frac{52}{360}

   = π × 5² × \frac{52}{360}

   = π × 25 × \frac{52}{360}

   = \frac{25(52)\pi }{360}

   ≈ 11.34 units² ( to the nearest hundredth )

Alex_Xolod [135]

Answer:

Gross pay per days is 5h+8 dollars

Step-by-step explanation:

we are given

total gross pay =35h+56 dollars

total number of days =7

we know that

gross pay per day = ( total gross pay)/(total number of days)

we can plug values

gross pay per day is

=\frac{35h+56}{7}

we can simplify it

=\frac{7(5h+8)}{7}

=5h+8
