Answer:
Step-by-step explanation:
The formula for circumfrance is 2*(pi)*R and the formula for area is (pi)* R^2 or (pi) R-squared.
Circumfrance is 25.12 so....
25.12 = 2 * (pi) R........ you want to find R because you need it to find the area
R is about 4; it is 3.99797 .
You use the R that you goot from cirdumfrance to find area.
Area = (pi) (4)^2 = 50. 265
or is you prefer a more precise answer, Area = 50.2145
Answer:
54
Step-by-step explanation:
10m +n^2 /4
= 10*5 + 4^2 /4
= 50 + 16/4
= 50 + 4
= 54
Answer:
x = 2
Step-by-step explanation:
-4(3 - 2x) + 2x = 2 x 4
-12 + 8x + 2x = 2 x 4
-12 + 8x + 2x = 8
-12 + 10x = 8
-12 + 12 + 10x = 8 + 12
10x = 20
x = 2
F/45 - 2/9 = 2/9....add 2/9 to both sides
f/45 = 2/9 + 2/9
f/45 = 4/9 ...multiply both sides by 45
f = 4/9 * 45
f = 180/9
f = 20 <===
