Answer:
50.29 in^2
Step-by-step explanation:
From the circumference we need to find the radius.
Since C = 2*pi*r, r = C / (2*pi).
Here, with C = 25 1/7 in, r = (25 1/7 in) / [ 2(22/7) ], or r = 4 in
The area of the cake is A = pi*r^2, or (here) A = (22/7)(4 in)^2 = 50.29 in^2
Answer:
Ratio of George age to Carl's age to Alex age = 1 : 12 : 4
Step-by-step explanation:
Let the age of Alex = A years
Age of George = G years
And age of Carl = C years
"Alex is 12 years older than George"
A = G + 12 ------(1)
"Carl is 3 times older than Alex"
C = 3A
C = 3(G + 12)
C = 3G + 36 ------(2)
"Sum of their ages is 68 years"
A + G + C = 68 ------(3)
By substituting the values of A and G in equation (3)
G + 12 + G + 3G + 36 = 68
5G + 48 = 68
5G = 20
G = 4 years
From equation (1),
A = 4 + 12 = 16 years
From equation
C = 3(4) + 36
C = 12 + 36
C = 48 years
Ratio of their ages = G : C : A
= 4 : 48 : 16
= 1 : 12 : 4
Answer:
Option A) angle bisector
Step-by-step explanation:
Angle Bisector:
- An angle bisector is a line that divides an angle into two equal parts.
- The angle bisector divide the angle in two equal parts.
- An angle bisector is equidistant from the sides of the angle when measured along a segment perpendicular to the sides of the angle.
- It cuts the angle into half.
- Thus, a sector can be divided into two equal sectors by drawing an angle bisector.
To divide the sector into two congruent sectors we can use the angle bisector construction.
Thus, the correct answer is
Option A) angle bisector
