2 answers:
Given:
Circumference of a circular plate = 24.5 inches.
To FInd:
Area of the circular plate
Solution:
By the formula of circumference
Circumference of a circular plate = 2πr
Where 'r' = radius of the plate
24.5 = 2
r = [Since π = 3.14]
r = 3.90 inches
We know the formula of a circular plate is,
Area = πr²
Therefore, A = (3.14)(3.90)²
A = 47.79 square inches
Therefore, area of the circular plate is 47.79 inches.

Answer:
Step-by-step explanation:
The given rectangle has diagonals have the endpoints P(-3, -2) ,I(4, -7) and A(4, -2) ,D(-3, -7)
The diagonals of the rectangle bisect each other so we use the midpoint formula to find their point of intersection.
The midpoint formula is;
We use any pair of endpoints of the diagonals to find the point of intersection.
Using A(4, -2) ,D(-3, -7)
