The radius of a circle is 4 feet. What is the length of a 90° arc? HELP ME PLEASE

Elza [17]

Answer:

6.3feet

Step-by-step explanation:

Given data

Radius= 4feet

The expression for the circumference of a circle is

C= 2πr

Substitute

C=2*3.142*4

C=25.136 feet

Also, a 90° arc is 1/4 of the circumference of a circle

Hence the length of the 90° arc is

=25.136/4

The perimeter of a triangle is 56. The side lengths are x + 4, 3x + 7, and x + 9. What is the value of x?

Sidana [21]

<h3><u>Answer:</u></h3>

x = 7.2

<h3><u>Step-by-step explanation:</u></h3>

Perimeter: Side 1 + Side 2 + Side 3

=> x + 4 + 3x + 7 + x + 9 = 56

=> 5x + 20 = 56

=> 5x = 56 - 20

=> 5x = 36

=> x = 7.2

<h3><u>Conclusion:</u></h3>

Therefore, the value of x is 7.2.
