Find the area of the circle to the nearest tenth. use 3.14 for pie. the circumference is 1.8cm

A = (3.14)(0.0821 cm²) = 0.2577 cm²

Step-by-step explanation:

Hint:  It's pi, or π, but definitely not pie.

If the circumference of this circle is 1.8 cm, then the radius of the circle must be r = 1.8 cm / (2π), because C = 2πr.

Then r = 0.2865 cm

and r² = 0.0821

The area of the circle is A = πr².  Using π = 3.14 and r² as shown above,

we get A = (3.14)(0.0821 cm²) = 0.2577 cm²

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!
