2. What is the area of a circle whose diameter is 14π cm?

Diameter = 14 cm

Radius(r) = Diameter/2

=> 14/2 = 7cm

Circumference of circle

=> 2 π r

=> 2 × \frac{22}{7}

7

22

× 7

=> 2 × 22

=> 44 cm

Therefore, circumference of circle= 44 cm.

Area of circle = π r ²

=> \frac{22}{7}

7

22

× 7 × 7

=> 22 × 7

=> 154 cm²

Therefore, Area of circle = 154 cm²

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
