Find the circumference and the area Of the circle with diameter 4 cm Use vale 3.14 to help with answer

circumference: 12.56 cm

area: 12.56 cm^2

Step-by-step explanation:

1. The formula to find the circumference of a circle is or . In this case, pi is approximated to 3.14, and the diameter is 4.

Therefore, the circumference is 12.56 cm.

2. The formula to find the area of a circle is , and in this case, pi is approximated to 3.14. Also, the radius is half the diameter: 4/2 = 2.

Therefore, the area is 12.56 cm^2.

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3
