Answer:
94.99
Step-by-step explanation:
Hi,
The formula to find the area of a circle is: A = πr²
So...
A = 3.14 (r)²
The radius of the circle is 5.5 because half of the diameter is the radius.
A = 3.14 (5.5)²
A = 3.14 (30.25)
A = 94.985 rounded is 94.99
I hope this helps :)
Answer: -20, 48
Step-by-step explanation: 5 x -4 = -20 6 x 8 = 48
Proof with explanation:
We know that the sum of first 'n' terms of a Geometric progression is given by
where
a = first term of G.P
r is the common ratio
'n' is the number of terms
Thus the sum of 'n' terms is
Now the sum of first '2n' terms is
Now the sum of terms from 
to 
term is 
Thus the ratio becomes
Answer:
y = 1/3a
Step-by-step explanation:
y = ka
1 = 3k
k = 1/3
Confirm constant: (4-1)/(12-3) = 3/9 = 1/3
1 = 3(1/3) + b
1 = 1 + b
b = 0
y = 1/3x or 1/3a
