the diameter is a circle is 16in. Find it’s circumference in terms of π.
C= ________in
According to the question,
Diameter of circle = 16 inWe are asked to calculate it’s circumference in terms of π.
★ Circumference of circle = 2πr
___________________________________
Let us first calculate the radius of the circle.
→ Diameter = 2 × Radius
→ 16 in = 2r
→ r = 16 in ÷ 2
→ r = 8 in
___________________________________
Substituting values in the formula of circumference,
→ C = 2πr
→ C = (2 × π × 8) in
→ C = 16π in
Therefore, 16π inches is the required answer.
Place an X in the table to match the diameter of each circle with its approximate area.
Use 3.14 for 11.

I need some help finding the volume of a sphere with a diameter of 18.6cm. The website says the answer I got from my calculator was wrong! Help would be greatly appreciated!
Answer:
V = 3,367.6 cm³
Step-by-step explanation:
Diameter of sphere (D) = 18.6 cm
radius (r) = ½(18.6) = 9.3
π = 3.14
Formula for volume of a sphere = ⁴/3πr³
Plug in the values
V = ⁴/3 × 3.14 × 9.3³
V = ⁴/3 × 3.14 × 804.357
V = (4*3.14*804.357)/3
V = 3,367.57463
V = 3,367.6 cm³ (nearest tenth)

There is just enough water in the container to exactly fill the
hemisphere. The container is held so that the point of the cone
is down and the altitude of the cone is exactly vertical. Find the
height of the water in the cone. Round to the nearest tenth.
Answer: hello your question is Vague hence I will provide a general solution. in which you can input your values into and get your answer.
answer = h = 3 ( V / π r^2 )
Step-by-step explanation:
The volume of a cone is exactly the volume of a hemisphere, given that the radius and height are the same .
The height of the water in the cone = height of the hemisphere / height of cone ( given that the water completely fills the hemisphere )
∴ h = 3 ( V / π r^2 )
solve 3x by 4 - 2x+5 by 3 = 5 by 2
Answer:
50
Step-by-step explanation:
The given equation is,
→ 3x/4 - (2x + 5)/3 = 5/2
→ 3x × 3 - 4(2x +5)/12 = 5/2
→ 9x - 8x -20/12 = 5/2
→ (x - 20)/12 = 5/2
→ x - 20 / 6 = 5
→ x - 20 = 30
→ x = 20 + 30
→ x = 50
• Hence the value of x is 50 .Answer:
x=50

Closest to the shaded area
Answer:
B) 30.9
Step-by-step explanation:
So, because the radius is 6, we know the diameter is 12, meaning we know each side is 12, so the total area of the square is 144.
To find the area of a square we should use pi(r) ^2 which is pi(6) ^2 which is 113.09. to find the area of the shaded are we would subtract these. 144- 113.09 this gets us 30.91, this is closest to B) 30.9
Ferris wheel diameter was 250 feet. Calculate it’s radius. If 40 steel rods were joined at the centre find the total steel required?
Answer:
785.5ft
Step-by-step explanation:
Given data
Diameter= 250ft
Radius= D/2= 250/2= 125ft
The total steel required can be found from the Circumference
C= 2πr
C= 2*3.142*125
C= 785.5ft
Hence the total steel required is 785.5ft

Answer:
area = 32
perimeter = 30
Step-by-step explanation:
Formulas:
Area of a parallelogram: A = bh
Perimeter of a parallelogram: P = 2 ( b + s )
Where h = height s = slant height and b = base length
Define:
b = 8
h = 4
s = 7
Plug in given values into formulas and calculate
A = (8)(4)
8 * 4 = 32
A = 32
P = 2 ( 8 + 7 )
8 + 7 = 15
2(15) = 30
P = 30

Let’s figure out one more adjustment for the butterscotch chip cookies. The butterscotch chip cookie recipe calls for 12 ounces of chips for every 2 cups of flour. How many ounces of chips are needed if 3 cups of flour are added?
Remember to keep your units consistent.
I believe it would 18 ounces of chips for 3 cups of flour. If you take half of 12 ounces then you get 6 ounces per cup of flour. Adding 6 ounces to the 12 would get us the total of the 18 ounces.
Simplify the ratio-
2kg : 3kg : 1.5 kg
Answer:
1.33kg : 2kg : 1kg
Step-by-step explanation:
2kg : 3kg : 1.5 kg
Given data
We have the ratio
2kg : 3kg : 1.5 kg
Let us reduce the ratio further
2/1.5: 3/1.5 : 1.5/1.5
1.33kg : 2kg : 1kg
Hence the simplified ratio is 1.33kg : 2kg : 1kg

The formula for the area of a triangle is 1A bh2=, where b is the length of the base and his the height. Rearrange the formula to isolate h
Answer:
h = 2A/b
Step-by-step explanation:
Area of a triangle, A = 1/2bh
Where,
b = base of the triangle
h = height of the triangle
Rearrange the formula to isolate h
A = 1/2bh
Multiply both sides by 2
2 * A = 2 * 1/2bh
2A = bh
Divide both sides by b
2A / b = bh / b
2A / b = h
Therefore,
h = 2A/b

Ann is twice as old as mary and three times as old as donald. Together their ages total 99. How old is ann?
Answer:
54 years
Step-by-step explanation:
Given that :
Let :
Ann's age = x
Mary's age = x/2
Donald's age = x/3
x + x/2 + x/3 = 99
Take the L. C. M
(6x + 3x + 2x) / 6 = 99
11x / 6 = 99
11x = 99 * 6
11x = 594
x = 594 / 11
x = 54
Hence, Ann is 54 years
