A circle has a diameter of 24 inches. What is the area of the circle, rounded to the nearest tenth?

area of a circle  = 452inches²

Step-by-step explanation:

diameter of a circle = 24inches

area of circle = πr²

we were not given  radius , we were given diameter,

to covert diameter to radius we will divide the diameter by 2

r = d/2

r = 24/2

r = 12inches

area of a circle  = π × (12)²

area of a circle  = π × 144

note the value of π  is equal to 22/7 or 3.14

area of a circle  = 3.14 ×144

area of a circle  = 452.16 inches²

area of a circle approximately to the nearest tenth

= 452inches²

16

step-by-step explanation:

2 x 40 = 80

80/5

= 16

the correct functions are

h(x) = 3x + 2  

g(x) = 2^x

step-by-step explanation:

i proceed to calculate the different values ​​of k (x)

case 1)  k(x) = g(x) ∘ h(x)

g(x) ∘ h(x)=g(h(x))

k(x) = [2]^[3x + > is the option  4. k(x) = 2^(3x + 2 )

case 2)  k(x) = g(x) + h(x)

k(x) = [2^x]+[3x + 2]=2^x+3x+> is the option  1.) k(x) = 2^x + 3x + 2

case 3)k(x) = h(x) ÷ g(x)

k(x) =  [3x + 2]/[2^x]=3x/(2^x)+2/(2^x)=3x*(2^-x)+2^(1-x)

is the option  3.)   k(x) = (3x)2^(-x) + 2^(-x + 1 )

case 4)k(x) = g(x) - h(x)

k(x) =  [2^x]-[3x + 2]=2^x-3x-> is the option  2.) k(x) = 2^x - 3x - 2 

case 5)  k(x) = g(x) × h(x)

k(x) = [2^x]*[3x + > is the option  5.) k(x) = 2^x(3x + 2)

case 6)k(x) = h(x) ∘ g(x)

h(x) ∘ g(x)=h(g(x))

k(x)=3*[2^x]+> is the option  6. k(x) = 3(2^x) +2
