Answer:

area of the circle = 3.14 square units

Step-by-step explanation:

Circumference of the circle formula is $2\pir$

where r is the radius of the circle

given circumference = 6.28

$2\pir$ = 6.28

Value of pi is 3.14

2*3.14 * r= 6.28

6.28 r = 6.28

divide by 6.28 on both sides

r = 1

radius = 1

Area of the circle = $\pi r^2$

= 3.14 *1*1 = 3.14

6 students want lemonade and 12 students

Ksenya-84 [330]

Answer:

2:1

Step-by-step explanation:

well we show ratio by the sign ' : '

ratio of iced tea to lemonade= 12:6

now we reduce it to minimum by dividing it with same number.

12 is divisible by 6

so,

the reduced form is = 2:1

therefore,

ratio of the number of students who want iced tea to the number of students who want lemonade = 2:1.

Find the area of the circle with a circumference of 50.24 units help me plz

swat32

Circumference of a circle=diameter times pi

50.24=d(3.14)
d=16

radius is half of diameter so radius is 8

Area of a circle=pi(r^2)

(3.14)(8^2)=(3.14)(64)=200.96
