A rectangle is placed around a semicircle as shown below. The length of the rectangle is 8 cm. Find the area of the shaded region. Use the value 3.14 for at, and do not round your answer. Be sure to include the correct unit in your answer.
PLEASE HELP
Answers
Answer:
Area of the shaded region = 6.88 cm²
Step-by-step explanation:
Area of the shaded region = Area of the rectangle - Area of the semicircle
Area of the rectangle = Length × Width
Length of the rectangle = AD = 8 cm
Width of the rectangle = OP = 4 cm [OP, OB and OC are the radii of the circle which are equal in measures]
Area of the rectangle = 8 × 4 = 32 cm²
Area of the semicircle = [tex]\frac{1}{2}\pi r^{2}[/tex]
= [tex]\frac{1}{2}\pi (OP)^{2}[/tex]
= [tex]\frac{1}{2}\pi (4)^{2}[/tex]
= 25.12 cm²
Area of the shaded region = 32 - 25.12
= 6.88 cm²

Step-by-step explanation:
The area of a triangle is given by [tex]A=\frac{1}{2}\cdot b\cdot h[/tex].
Substituting given values, we have:
[tex]240=\frac{1}{2}\cdot b\cdot 15,\\480=15b,\\b=\frac{480}{15}=\boxed{32\:\mathrm{in}}[/tex]
Answer:
Base=32 inches
Step-by-step explanation:
Area=240
Height= 15
Area= b*h/2
2A/h=b
2*240/15=b
b=32
help please dont add a link or you'll get reported
Answers
Explanation:
Ok so surface area is just adding up all the area of each faces. Just look at what I do below:
Area of the rectangular base:
10 • 6= 60
Area of the front triangle facing us:
1/2 • 12 • 10= 60
Multiply 60 by 2 cause there is still another similar triangle at the back- 60 • 2= 120
Area of the triangle facing right:
1/2 • 8 • 6= 24
Multiply 25 by 2 case there is still another similar triangle facing on other side(left)
24 • 2= 48
Add them all up together
60 + 120 + 48= 228

The can shown has a diameter of 3 inches and a height of 5 inches. Find the lateral surface area of the can.
Answers
Answer:
Lateral surface area of can = 47 inch² (Approx.)
Step-by-step explanation:
Given:
Diameter of given can = 3 inches
Height of given can = 5 inches
Find:
Lateral surface area of can
Computation:
Radius of can = 3 / 2 = 1.5 inch
Lateral surface area of can = Lateral surface area of cylinder
Lateral surface area of cylinder = 2πrh
Lateral surface area of can = 2πrh
Lateral surface area of can = 2(3.14)(1.5)(5)
Lateral surface area of can = 47.1
Lateral surface area of can = 47 inch² (Approx.)

The angle m∠CBE between the intersection of the chord and tangent line is equal to 41°
How to calculate for angle between the intersection of a chord and a tangent.To calculate for the angle between the intersection of a chord and a tangent we need to know the measure of the intercepted arc, and then divide it by 2 to get the angle.
If the measure of the arc CAB is given to be equal to 278°, then the measure of intercepted arc BC is calculated as:
arc BC = 360 - 278
arc BC = 82°
angle CBE = 82°/2
m∠CBE = 41°
Therefore, the angle m∠CBE between the intersection of the chord and tangent line is equal to 41°

You buy a new motorcycle for $15,500. Its value depreciates by 8.5% each year. In how many years will it be worth only a tenth of what you paid for it?
a. 26
b. 27
c. 24
d. 25
Answers
Answer:
a. 26
Step-by-step explanation:
The formula for depreciation is given as
y = a(1 - r)^t
a = Initial value = $15,500
y = Current value = 1/10 of Initial value = $1,550
r = depreciation rate = 8.5% = 0.085
t = time in years = ?
Hence,
1550 = 15500(1 - 0.085)^t
1550 = 15500(0.915)^t
Divide both sides by 15500
1550/15500 =(0.915)^t
0.1 = (0.915)^t
Take the Logarithm of both sides
log 0.1 = log(0.915)^t
log 0.1 = t log (0.915)
Divide both sides by log 0.915
t = log 0.1/log 0.915
t = 25.920900964 years
Approximately Time t = 26 years
Option a is correct

Bob can type 2 letters in 4 hours while bill can do it in six. How many hours will it take them, working together, to type six letters
Answers
Answer:
7hr 12 min
Step-by-step explanation:
Given that
Bob can type 2 letters in 4 hours
while on the other hand bill can do it in six hours
We need to find out the no of hours in which they type 6 hours
So,
Bob's rate is
= 2 ÷ 4
= 1 ÷ 2 letter per hour
And,
Bill's rate is
= 2 ÷ 6
= 1 ÷ 3 letter per hour
Now
Together rate is
= 1 ÷ 2 + 1 ÷ 3 = 5 ÷ 6 letter per hour
We know that
rate × hours = production
Let us assume the hours be x
So,
(5 ÷ 6)x = 6
x = (6 ÷ 5) × 6
x = 36 ÷ 5
= 7 1 ÷ 5
= 7hr 12 min
