Answer:
13.) 314.2 in²
15.) 181.5 ft²
Step-by-step explanation:
The area of a circle is found using the equation:
A = πr²
In this equation, "π" represents the number pi (3.14....) and "r" represents the radius (half the diameter).
For 13.), you have been given the radius. Thus, you can substitute it into the equation and solve for "A".
A = πr²
A = π(10)²
A = π x (100)
A = 314.2 in²
For 15.), you have been given the diameter. To find the radius, you need to divide this value by 2. Once you find the radius, you can plug it into the equation and simplify like above.
diameter = 15.2 ft
radius = 7.6 ft
A = πr²
A = π(7.6)²
A = π x (57.76)
A = 181.5 ft²
Answer: Yes, It is 315, I'm 100% honest!
Answer: A
Step-by-step explanation: this is the only answer because the other two solutions are
A: 4>3 correct
B: 3>3 wrong
C: 2>3 wrong
The answer in this question is B The diagonals of the parallelogram are congruent because that's only possible for right angle quadrilaterals. We can say that the diagonals of the parallelogram are congruent. The diagonals of this figures have the same size and shape.
The value of b and c is 4 and 7.
<h3>What is algebra?</h3>
Algebra is the part of mathematics in which letters and other general symbols are used to represent numbers and quantities in formulae and equations.
Algebra is divided into different sub-branches such as elementary algebra, advanced algebra, abstract algebra, linear algebra, and commutative algebra.
Elementary algebra: elementary algebra, branch of mathematics that deals with the general properties of numbers and the relations between them. Algebra is fundamental not only to all further mathematics and statistics but to the natural sciences, computer science, economics, and business.
From the given question,
This expression can also be written in the form of 
We will convert
to the required form:

Hence,
From the above equation we get the value of b and c is 4 and 7.
