Answer:
1056.25π square units
Step-by-step explanation:
A few formulas an definitions which will help us:
(1) 
, where c is the circumference of a circle and d is its diameter
(2) 
, where A is the area of a circle with radius r. To put it in terms of d, remember that a circle's diameter is simply twice its radius, or mathematically, (3) 
.
We can rearrange equation (1) to put d in terms of π and c, giving us (4) 
, and we can make a few substitutions in (2) using (3) and (4) to get use the area in terms of the circumference and π:
We can now substitute c for our circumference, 65, to get our answer in terms of π:
Answer:
4/3
Step-by-step explanation:
7x + 4 = 10x
4 = 3x
x = 4/3
