Answer:

C = 21.98 ft^2

A = 38.465 ft^2

Step-by-step explanation:

The diameter is 7 ft

The radius is 1/2 of the diameter so 1/2 *7 = 3.5 ft

Circumference = pi*d

C =pi* 7

C =3.14 *7

= 21.98 ft^2

A = pi*r^2

= 3.14 (3.5)^2

= 3.14 (12.25)

= 38.465 ft^2

Does anyone know how to do these maths question???

Dmitry_Shevchenko [17]

Answer:

Part 1) $f(g(x))=3(x^2)+2$

Part 2) $g(f(5))=289$

Step-by-step explanation:

we know that

A composite function is a function that depends on another function. A composite function is created when one function is substituted into another function

we have

$f(x)=3x+2$

$g(x)=x^{2}$

Part 1) Determine f(g(x))

To find f(g(x)) substitute the function g(x) as the variable in function f(x)

$f(g(x))=3(x^2)+2$

Part 2) Determine g(f(x))

To find g(f(x)) substitute the function f(x) as the variable in function g(x)

$g(f(x))=(3x+2)^2$

For x=5

$g(f(5))=(3(5)+2)^2$

$g(f(5))=289$

Answer:

Line symmetry

Step-by-step explanation:

If you drew a straight line across the figure horizontally, you would see that both halves are symmetrical.
