The area of a circle with radius r is πr². So you need to find r such that
πr² = 56π
⇒ r² = 56
⇒ r = √56 = 2√14
She started at 6:35 p.m,
because minus 10 from the 7:10, you just have 7 now right? And she only has 25 min left. then minus 25 from 60 to get your answer. it is 6 35 pm.
You could multiply the length that they have given you by 2 and subtract that from the perimeter. That gives you the total length of the missing side and divide it by 2 to get one side.
Answer:
See below
Step-by-step explanation:
Quadratic formula :
x = [-b ± sqrt ( b^2 - 4ac) ] / 2a
for this problem a = 3 b= - 5 c = - 4
substitute in the values and compute:
<u> x= 5/6 ± sqrt (73)/6 </u>
The correct answer is ( A )
