Two formulas here:
Area = πr²
Circumference = 2<span>πr
So first we solve for r from area:
25</span>π = πr²
25 = r²
r = 5
So we know that radius is 5 cm.
Now substitute r to 5 in circumference formula:
C = 2π(5) = 10π
Final answer: 10π cm
Hope this helps.
Answer:
11 and 12
Step-by-step explanation:
The two numbers will be called x and y. The sum of x and y is 23 and the difference is 1.
x + y = 23
x - y = 1
Add the equations together
x + y + x - y = 23 + 1
2x = 24
x = 12
y = x - 1
y = 11
x·1/2·7/8·6/7·1/2 = 12 --> x = 64 Stickers
Answer:
16
Step-by-step explanation:
1/4 pie=4
2/4 pie= 8
3/4 pie= 12
4/4pie= 16
No.
8 can be divided by 6 one more time. the correct answer should be 49 r2
