Answer:
Step-by-step explanation:
The thing with the arc length formula, s = rt, is that t is the angle in radians. Ours is in degrees, so we have to change it:
36 × 
So the formula we use to solve for r is:

Multiply both sides by 5 over pi to get that

Answer:
The area of the shape is 693 m^2
Step-by-step explanation:
Here, we want to calculate the area of the given shape
Mathematically, what we have to do here is to multiply the base of the shape with the height
We have this as;
21 * 33 = 693 m^2
<h3>
Answer: Choice C) $1,444.50</h3>
========================================================
There are two methods to get the answer.
The slightly longer method is to take 7% of the original price to get
7% of 1350 = (7/100)*1350 = 0.07*1350 = 94.50
The sales tax is $94.50
Add this onto the original price to get 1,350+94.50 = 1,444.50
----------------------------
A shortcut is to multiply the original price by 1.07
The multiplier 1.07 represents a 7% increase since
- 1 = 100%
- 0.07 = 7%
- 1.07 = 1 + 0.7 = 100% + 7%
So we will have 1.07*1350 = 1,444.50
