Answer:
<em>$2,025.78 </em>
Step-by-step explanation:
I = Prt ⇒ P =
2.25% = 0.0225
P = 45.58 ÷ ( 0.0225 × 1 ) ≈ <em>$2,025.78</em>
Answer: 
Step-by-step explanation:
Given
The central angle of a sector measures 
The radius of the circle is 
The area of the sector is given by

Insert the values

Answer:
23
Step-by-step explanation:
Since 2/10 = 4/20, we know that a-3 = 20, so a = 20 + 3 = 23.
x^3=54 (Subtract 3 from both sides)
x = 3rd power cube root of 54 (Cube root both sides)
27 = 3^3 (3x3x3) therefore
x = (3) (3rd power cube root of 2)
SA of half of this cylinder:
1/2*2pi(3)^2+1/2*2pi*3*25
9pi+75pi
84pi cm^2 OR 263.89 cm^2
