Given:
diameter = 14 inches
radius = 14 inches / 2 = 7 inches
Circumference of a circle = 2 π r = 2 * π * 7inches = 14 inches * π
Area of a circle = π r² = π * (7in)² = π * 49in²
C = 14π and A = 49π
Answer:
The perimeter of EFGH is 30.5
Step-by-step explanation:
figure ABCD is similar to figure EFGH (hence the ~ sign)
A -> B= <u>12</u>
B -> C= <u>12 </u>
C -> D= <u>12</u>
A -> D= <u>25</u>
EFGH has sides that are half of the size of ABCD
there are two ways you can solve this:
A) divide the perimeter of ABCD by 2 (making it half)
61 / 2 = 30.5
or
B) adding all of the sides together
E -> F =6 so therefore so do F-> G and G -> H
6 + 6 + 6 + 12.5 = 30.5
