A cake has a circumference of 25 1/7 inches. What is the area of the cake? Use 22/7 to approximate pi. Round to the nearest hund
Diano4ka-milaya [45]
If circumference = (2 * PI * radius) then we solve for radius
radius = circumference / (2 * PI)radius = 25.142758 / 22/7 * 2radius =  <span><span>4.00 </span> </span> <span><span> </span> </span>
circle area = PI * radius^2circle area = 22/7 * 4^2circle area = 22/7 *16 <span><span><span>circle area = 50.29 square inches

SVETLANKA909090 [29]

Answer:

A system of the equation of a circle and a linear equation

A system of the equation of a parabola and a linear equation

Step-by-step explanation:

Let us verify our answer

A system of the equation of a circle and a linear equation

Let an equation of a circle as x^2+ y^2 = 1 ..........(1)

Let a liner equation Y = x ............(2)

substitute (2) in (1)

x^2 + x^2 = 1\\2x^2 = 1\\

x^2 = \frac{1}{\sqrt{2} } \\x = +\frac{1}{\sqrt{2} } , -\frac{1}{\sqrt{2} }  so Y = +\frac{1}{\sqrt{2} } , -\frac{1}{\sqrt{2} }

so the two solution are ( (\frac{1}{\sqrt{2} } ,\frac{1}{\sqrt{2} }) (-\frac{1}{\sqrt{2} }, -\frac{1}{\sqrt{2} })

A system of the equation of a parabola and a linear equation

Let equation of Parabola be y^2 = x

and linear equation y = x

substitute

x^2 = x\\x^2 - x= 0\\x(x-1) = \\x = 0 , 1

Y = 0,1

so the two solutions will be (0,0) and (1,1)

Complete the first step in writing the equation of a circle in graphing form.
harkovskaia [24]
I think its x² - 2x + y² + 6y - 6 = 0 x² - 2x + y² + 6y = 6 (x² - 2x + 1) + (y² + 6y + 9) = 6 + 1 + 9 (x - 1)² + (y + 3)² = 16 center: (h, k) = (x, y) = (1, -3) radius: 4
