3. the circumference of a circle is 2.2 m. calculate the area of the circle.

The area of circle is 0.38465 square meter

Solution:

The circumference of a circle is 2.2 m

We have to find the area of circle

Let us first find the radius of circle

The circumference of circle is given as:

Where, "C" is the circumference of circle

"r" is the radius of circle

is a constant equal to 3.14

Substitute c = 2.2 in above formula

Thus radius of circle is 0.35 meter

The area of circle is given as:

Substitute r = 0.35

Thus area of circle is 0.38465 square meter

just needed some points but try socratic

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
