Answer:
Step-by-step explanation:
Formula =P×R×T=I
P×11/100×6=4500
66/100p=4500
100/66×66/100=4500×100/66
P=6818.1818.......
=6818.18
The answer to the problem is 0.67

2) Rectangular shape is square shape patio !
<u>Step-by-step explanation:</u>
Here we have , the area of Bianca’s rectangular backyard patio is represented by the expression x2 – 18x + 81, and the length of the patio is represented by the expression x − 9: We need to find
1. what is the expression for the width of the patio? Explain and show all work.
We know that area of rectangle = 
⇒ 
Factorizing RHS:
⇒ 
⇒ 
⇒ 
⇒ 
2. what special rectangular shape is the patio?
Now , we see that

A rectangle whose length & width are equal is known as a square ! Hence , Rectangular shape is square shape patio !
Answer:
S = 2π(36) + 2π(6)(8)
S = 2(3.14)(36) + 2(3.14)(6)(8)
Step-by-step explanation:
The surface area of a cylinder is the sum of the area of the base and the lateral area. A cylinder has 2 circular base .
Surface area = 2πr² + 2πrh
surface area = 2πr(r + h)
where
r = radius
h = height
surface area = 2πr(r + h)
r = 6 cm
h = 8 cm
The equation to find the surface area is represented below.
Surface area = 2πr² + 2πrh
S = 2π (6²) + 2π (6)(8)
S = 2π(36) + 2π (6)(8)
Assuming π is given as 3.14 the equation will be as follows
S = 2(3.14)(36) + 2(3.14)(6)(8)
