Answer:
the area would be 36(pi) since you can't find out the exact value of pi (22/7) and where it would terminate so thats the most exact answer you can get. The circumference would be
Step-by-step explanation:
12/2 = 6
Area = (pi)radius^2
6^2 = 36
36(pi)
Circumference: (pi)d
12(pi)
For approximate area you multiply r^2 by 3.14
For approximate circumference you multiply diameter by 3.14
Answer: " b = 3 ⅕ ; or, write as: 3.2 .
_____________________________________
Given: "A = (1/2) * b * h " ;
↔ A = (b * h) / 2
2A = (b*h) ;
2A/ h = b ;
↔ b = (2A) / h ;
Given A = 48 ; and h = 30 ; Plug in these values; and solve for "b" ;
→ b = (2*48) / 30 ;
= 96/30 ;
= (96÷6) / (30÷6) ;
→ b = 16/5 ; = 3 <span>⅕ ; or, write as: 3.2 .

Answer:
f(x)= 25(1 + 0.20)^t
Step-by-step explanation:
The formula- <em>f(x)= a(1+r)^x</em>
<em />
a= initial amount (25)
r= growth rate (20%... 0.20)
x= # of times (we don't have that in here)
When you plug in the values, you get
f(x)= 25(1 + 0.20)
hope this helps!!
Solve for x
4 12
--- = --- 4x=36 36/4=9 x=9 = PQ=9in
3 x
4 18
--- = --- 4x=54 54/4=13.5 x=13.5 QR=13.5in
3 x
4 24
--- = --- 4x=72 72/4=18 x=18 PR=18in
3 x
18+13.5+9 = 40.5
Therefore, the perimeter of ΔPQR = 40.5inches
The answer is A because 9 x 9 x 9 = 729. The exponent above the 9 means to multiply the base (9) 3 times.
