Trent Ordered a pizza. The circumference of the pizza is 25.12 inches. The radius of the pizza is 4 inches, trent understands that pi is the ratio of the circumference compared to the diameter. So trent says that pi =23.12/4, is he correct, explain your work

Trent is wrong.

This is because:

π = 25.12/2 × 5

π = 25.12/8

Step-by-step explanation:

A pizza is circular is shape, the formula for the circumference of a circle is :

C = 2× π × r

Making π the subject of the formula

π = C/2r

The circumference of the pizza is 25.12 inches. The radius of the pizza is 4 inches,

Hence:

π = 25.12 inches/ 2 × 4 inches

π = 25.12/8

From the calculation above, Trent is wrong.

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
