Jenny's pizza is circular and has a 30 cm radius. Her slice creates an arc with a central angle of 120°. What is the area of Jenny's slice of pizza?

the area of Jenny's slice of pizza is 942 cm²

Step-by-step explanation:

Since the pizza is circular, a slice of the pizza represents a sector of a circle. To determine the area of the slice, we would apply the formula for determining the area of a sector which is expressed as

Area of sector = θ/360 × πr²

Where

θ represents the central angle.

r represents the radius of the circle.

π is a constant whose value is 3.14

From the information given,

Radius, r = 30 cm

θ = 120 degrees

Area of sector = 120/360 × 3.14 × 30²

= 942 cm²

step-by-step explanation:

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
