I need some help with this
Ivenika [448]

Answer:

a) 6.1 feet

b) 12.6 feet

Step-by-step explanation:

Using trigonometric ratios we know that:

sin = \frac{opp}{hyp}\\cos = \frac{adj}{hyp}\\tan = \frac {opp}{adj}

AKA SohCahToa.

To find the height, we will use sine.

sin(26^o)= \frac{x}{14}\\14*sin(26^o)=\frac{x}{14}*14\\14sin(26^o)=x\\x=6.14

To find the length we will use cosine.

cos(26^o) = \frac{x}{14}\\14*cos(26^o)=\frac{x}{14}*14\\14cos(26^o)=x\\x=12.6

Part A:

Circumference = πd

Circle A: d = 7
7π = 21.98
π = 21.98/7 = 3.14

Circle B: d = 6
6π = 18.84
π = 3.14

Part B:

Area = πr^2

Circle A: r = 3.5
π3.5^2 = 38.465
12.25π = 38.465
π = 3.14

Circle B: r = 3
π3^2 = 28.26
9π = 28.26
π = 3.14

Part C: The value of π is the same in circles A and B
