What is the area of a circle with a diameter of 150 cm?

5625π cm²

Step-by-step explanation:

Radius = 150 / 2 = 75 cm

Area = πr² = π(75)² = 5625π cm²

17662.5 (I used 3.14 instead of the regular pi but if you need to use pi the answer would be 17671.4587)

Step-by-step explanation:

First, you grab the diameter then divide that by 2 (that gives you the radius of the circle) Then, multiple 75² * 3.14 (or pi) to give you the answer!

Hope this helps! Good luck!

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!
