Answer:
50.29 square inches.
Step-by-step explanation:
Given:
Sara is cutting circles out of pieces of cardboard.
She uses a rectangular piece of cardboard that is 8 inches by 10 inches.
Question asked:
What is the area of the largest circle she could make?
Solution:
Here given length of piece of cardboard is 10 inches and breadth is 8 inches, to draw the largest circle, we have to draw the circle touching the boundary of the breadth of the rectangular cardboard and hence breadth will be considered as diameter and it will be the maximum diameter of the circle.
Now, we will find the area of the largest circle by taking breadth as the maximum possible diameter:
Breadth = Diameter = 8 inches ( given )
Radius = half of diameter ,


Therefore, area of the largest circle she could make is 50.29 square inches.
Answer:
y=68.38172757
Step-by-step explanation:
Take the inverse cosine of both sides of the equation to extract
y from inside the cosine.
y=arccos(7/19)
y=68.38172757
The cosine function is positive in the first and fourth quadrants. To find the second solution, subtract the reference angle from
360 to find the solution in the fourth quadrant. y=360−68.38172757
y=68.38172757+360n,291.61827242+360n, for any integer n
Answer:
a = 2, b = - 6, c = 11
Step-by-step explanation:
The standard form of a quadratic equation is
ax² + bx + c = 0 : a ≠ 0
Compare the coefficients of the terms in standard form to
2x² - 6x + 11 = 0 ← in standard form
Thus a = 2, b = - 6 and c = 11
