Answer:
Area pf the regular pentagon is 193
to the nearest whole number
Step-by-step explanation:
In this question, we are tasked with calculating the area of a regular pentagon, given the apothem and the perimeter
Mathematically, the area of a regular pentagon given the apothem and the perimeter can be calculated using the formula below;
Area of regular pentagon = 1/2 × apothem × perimeter
From the question, we can identify that the value of the apothem is 7.3 inches, while the value of the perimeter is 53 inches
We plug these values into the equation above to get;
Area = 1/2 × 7.3× 53 = 386.9/2 = 193.45 which is 193
to the nearest whole number

Answer:
Radius r = ±√52
Coordinates of center =
Step-by-step explanation:
Points to remember
Equation of a circle passing through the point (x1, y1) and radius r is given by
(x - x1)² + (y - y1)² = r ²
<u>To find the radius and coordinates of center</u>
It is given that an equation of circle,
(x - 4)² + (y + 6)² = 52
Compare two equations,
we get r ² = 52
r = ±√52
(x - x1)² = (x - 4)² then x1 = 4
(y - y1)² = (y + 6)² then y1 = -6
Coordinates of center = (4, -6)
