*PL HELP* A triangle has sides that measure 7 units, 6 units, and 9.22 units. What is the area of a circle with a circumference that equals the perimeter of the triangle? Use 3.14 for π, and round your answer to the nearest whole number.

157 units2
39 units2

39 untits 2

Step-by-step explanation:

Hi, to answer this question, first we have to calculate the perimeter (sum of sides) of the triangle:

Perimeter: 7+6+9.22 = 22.22 units

Then we have to apply the circumference (C) formula:

C = π x diameter

Since C = perimeter of the triangle:

22.22 = 3.14 d

22.22 /3.14 =d

7.08 = d

Finally, we apply the next formula:

Area of a circle = π (d/2)^2

Replacing:

A = 3.14 (7.08/2)^2 = 39.30 units2 = 39 units 2

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
