Answer:
A=103.13cm
Step-by-step explanation:
Formula: A= c^2/4π (C being the circumference and ^2 means it's squared)
Plug in what you know: 36^2/4π
1296/4π= 103.13
Answer:
The number of student tickets was 
The number of general admission tickets was 
Step-by-step explanation:
Let
x----> the number of student tickets
y---> the number of general admission tickets
we know that

---> equation A
----> equation B
Substitute equation A in equation B and solve for y





Find the value of x

Step-by-step explanation:
what is the problem ? this is very straight forward with a calculator :
cos(64°) = y/8
y = 8×cos(64°) = 8×0.438371147... = 3.506969174... ≈
≈ 3.5

<em><u>Solution:</u></em>
Given that,

We have to factor out terms and write as a product of 2 binomials and monomial
A monomial is a mathematical expression with only one term, while a binomial is a mathematical expression with two terms.
From given expression,

3 and a are common factors in second bracket

Hence, the product of two binomial is written in two binomial and a monomial
