Required
Determine h, the height of the small one
To do this, we make use of the following equivalent ratios;

This gives:

Express as fraction

Simplify

Cross multiply


Area of circle= pi times radius^2
diameter=2 times radius
radius=diameter/2
diameter=12
radius=12/2
radius=6
pi times r&+^2
pi times 6^2
pi times 36
aprox pi=3.14
113.04 in^2
Answer:
C
Step-by-step explanation:
x² + 3x - 10
p + q needs to equal the b-value.
Since b = 3, then the sum of p = -2 and q = 5 works.
⇒ (x - 2)(x + 5)
The answer to this question is 3 19/20
