Find the area of a circle whose radius is 12 inches

A≈452.39

Step-by-step explanation:

A=πr^2

A=π12^2

A=π144

A≈452.39

R = 12

Area = pi r²

Area = 22/7 × 12 × 12 = 452.57 in²

the transverse axis of a hyperbola is the line that contains the two vertices and the two focuses.

in this example (hyperbola of equation x^2/2 - y^2/4 = 1), the transverse axis is the  x-axis  . 

step-by-step explanation:

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
