The circle has center 0. Its radius is 3 ft, and the central angle a measures 50% What is the area of the shaded region? Give the exact answer in terms of 7, and be sure to include the correct unit in your answer.

1.25π

Step-by-step explanation:

Hello There!

The area of a sector can be found using this formula

where 0 = angle and r = radius

so given the measures r = 3 and 0 = 50 all we have to do is plug in the values into the formula

so...

so the area of the sector = 1.25π

Note: it says to leave your answer in terms of pi so we do not have to apply pi

d, x=8

step-by-step explanation:

simplifying

4x + -5 = 2x + 11

reorder the terms:

-5 + 4x = 2x + 11

reorder the terms:

-5 + 4x = 11 + 2x

solving

-5 + 4x = 11 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-5 + 4x + -2x = 11 + 2x + -2x

combine like terms: 4x + -2x = 2x

-5 + 2x = 11 + 2x + -2x

combine like terms: 2x + -2x = 0

-5 + 2x = 11 + 0

-5 + 2x = 11

add '5' to each side of the equation.

-5 + 5 + 2x = 11 + 5

combine like terms: -5 + 5 = 0

0 + 2x = 11 + 5

2x = 11 + 5

combine like terms: 11 + 5 = 16

2x = 16

divide each side by '2'.
