The cylinder is 20cm high and radius of its circular face is 3cm What is the total perimeter and area of the whole net?
Answers
Answer: [tex]52\ cm,\ 176.55\ cm^2[/tex]
Step-by-step explanation:
Given
The cylinder is 20 cm high
The radius of the cylinder is [tex]r=3\ cm[/tex]
The total area of the figure is the sum of the rectangle and two circles
[tex]\Rightarrow \text{Perimeter P=}2[h+2r]\\\Rightarrow P=2[20+6]\\\Rightarrow P=52\ cm[/tex]
The total area of the figure is
[tex]\Rightarrow \text{Area A=}h\times 2r+2\pi r^2\\\Rightarrow A=20\times 6+2\times \pi \times 3^2\\\Rightarrow A=120+18\pi\\\Rightarrow A=176.55\ cm^2[/tex]

BA) = 0.93, what is P(B)?
O 0.41
O 0.93
O None of the other answers are correct
O 0.58
O 0.67
Answers
Answer:
Step-by-step explanation:
you’re given A=0.62 and B/A=0.93
you’re solving for B
substitute your A value of 0.62
B/0.62=0.93
same as B/0.62=0.93/1
now cross multiply
B= 0.62x0.93
B=0.5766
B=0.58

c=square root of a2+b2
but we are solving angle b
so
b2=c2-a2
b2=225-196
b2=29
b approximately = 5.39 Rounded up
Answer:
5.4
Step-by-step explanation:
c² = a² + b²
15² = 14² + b²
225 = 196 + b²
b² = 225 - 196
b² = 29
b = 5.4

A room measures 15 ft by 20 ft by 10 ft. If a basketball has a diameter of 9.6 inches, approximately how many basketballs will be needed to fill the room?
Answers
Answer:
10344.827586 basketballs
Step-by-step explanation:
A room measures 15 ft by 20 ft by 10 ft. If a basketball has a diameter of 9.6 inches, approximately how many basketballs will be needed to fill the room?
Step 1
We find the volume of the room
The room is rectangular in shape
Volume = Length × Width × Height
= 15ft × 20ft × 10ft
= 3000ft³
Step 2
Basket ball is spherical in shape
Volume of a sphere = 4/3πr³
Diameter = 9.6 inches
Radius = Diameter/2 = 9.6 /2 = 4.8 inches
Convert Radius from inches to ft
= 4.8inches/12
= 0.408333 feet
Volume of a sphere = 4/3 × π × 0.408333³
= 0.29 ft³
Step 3
3000 ÷ 0.29

The formula = () − applies to the demand of a product, where q is the number of units and P is the price of one unit. How many units will be demanded if the price is Rs. 18.00?
Answers
Answer:
4320 units quantities were demanded
Step-by-step explanation:
Given:
[tex]p = 90 (5) - \frac{q}{10}[/tex]
Required:
The units demanded when price = 18.00
This implies that:
[tex]p = 18.00[/tex]
So, we have:
[tex]p = 90 (5) - \frac{q}{10}[/tex]
[tex]18.00 = 90(5) - \frac{q}{10}[/tex]
Open bracket
[tex]18.00 = 450 - \frac{q}{10}[/tex]
Collect like terms
[tex]\frac{q}{10} = 450 - 18.00[/tex]
[tex]\frac{q}{10} = 432[/tex]
Solve for q
[tex]q = 432 *10[/tex]
[tex]q = 4320[/tex]
