The area of a circle is A = r^2pi
Since the area is equal to 121pi the equation would be, 121pi = r^2. To find r in terms of pi take the square root of 121, to find the radius. Then multiply that by two to get the diameter.
Answer:
10
Step-by-step explanation:
4 x 10 = 40
40 + 12 = 52
Answer: 81
Step-by-step explanation: 9 times 9 = 81
Answer:
$172.80
Step-by-step explanation:
$160.00 x 1.08=$172.80
25m+100−24m−75=68
Step 1: Simplify both sides of the equation.
25m+100−24m−75=68
25m+100+−24m+−75=68
(25m+−24m)+(100+−75)=68(Combine Like Terms)
m+25=68
m+25=68
Step 2: Subtract 25 from both sides.
m+25−25=68−25
m=43
Answer:
m=43
