Answer:
perimeter = 43.98cm
area = 76.96cm^2
Step-by-step explanation:
You take into account that the shaded regions are perfect circles, then, the total perimeter of the shaded regions are given by the circumference of both circles.
You calculate the circumferences, by using the following formula:
(1)
r: radio of the circles = (7/2)cm = 3.5cm
The total perimeter is twice the value of C in the expression (1). You replace r in (1), and calculate the total perimeter:
The perimeter of the shaded region is 43.98cm.
The area of the shaded region is twice the area of one of the circle, which is given by:
The total area of the shaded region is 76.96cm^2
Answer:
Explanation:
Given:
To Find:
Value of p=?
Solution:
Before solving this equation, we will use the method of BODMAS which states that we first solve the Bracket then Off then Division then Multiplier then addition and at last subtraction.
Now we will solve the both right and left hand side of the equation
Gruoping the like terms we get,
After solving the both right hand and left hand side of the equation
And we get the value of p as
3 inches and 2 inches, 6÷3 & 9÷3.
12×3=36 so divide 6 by 3 and 9 by 3
<span>The interior angles of any polygon always add up to a constant value, which depends only on the number of sides. We use the equation as follows:
</span>sum = 180 (n−2) degrees
sum = 180 (29 - 2) degrees
sum = 4860 degrees
Hope this answers the question. Have a nice day.
