I included work in photo below. Say u used cylinder volume formula
Answer:
7241.25 mm squared
Step-by-step explanation:
The surface area of a cylinder is denoted by: , where r is the radius and h is the height.
Here, we know that the diameter is 39.2 mm, and since diameter is twice the radius, then r = d/2 = 39.2/2 = 19.6 mm. We also know that the height is 39.2 mm
using this formula for surface area of cyclinder: 2πrh+2π
diameter = 2r --> 39.2 = 2r
so r= 19.6
The answer is 7241.25 mm squared.

The expression -320+15y represents a submarine that began at a depth of 15 feet below sea level and ascended at a rate of feet per minute. What was the depth of the submarine after 15 minutes?
Answers
Step-by-step explanation:
Given an expression that represents a submarine that began at a depth of 15 feet below sea level and ascended at a rate of feet per minute is as follows :
-320+15y
We need to find the depth of submarine after 15 minutes.
Put y = 15 in the above expression.
-320+15y = -320+15(15)
= -320 + 225
= -95
Hence, the submarine is below sea level at 95 feet.

Find the value of a5, given the sequence defined as: a1 = 32 an = (1/2)an-1
Answers
Answer:
a5 = 2
Step-by-step explanation:
If a1 = 32,
a1 = 1/2 a0 = 32
a0 = 64
With that, we know that
a0 = 64,
a1 = 32
so, a2 is definitely 16. From that, we may know the formula,
an = a0 (1/2)^n
a5 = a0 (1/2)^5
a5 = 64 (1/32)
a5 = 2

What is the width of the lid?
Answers
Answer:
The width of the lid is 15 cm
Step-by-step explanation:
The Perimeter of a Rectangle
Given a rectangle of width W and height H, the perimeter is calculated as:
P = 2(W + L)
Jon used 56 cm of ribbon to go around the edge of a rectangular lid. This means the perimeter is:
2(W + L) = 56
Dividing by 2:
W + L = 28
Since the lid was L=13 cm long, the width is:
W = 28 - 13 = 15
The width of the lid is 15 cm

The area of the given cloth is 1/6 yards².
What is an area?The measurement that expresses the size of a region on a plane or curved surface is called an area. Surface area refers to the area of an open surface or the boundary of a three-dimensional object, whereas the area of a plane region or plane area refers to the area of a form or planar lamina.So, the area of the cloth:
The length of the cloth is 5/9 yards.The breadth of the cloth is 3/10 yards.So, we know that it is a rectangular cloth.
Area of rectangle: l × bCalculate the area as follows:
l × b5/9 × 3/1015/901/6 yards²
Therefore, the area of the given cloth is 1/6 yards².

This is circle theorems I am not rly good at this
Answers
Answer:
m∠BCD = 24°
Step-by-step explanation:
By the theorem,
"Angle subtended by an arc at the center of the circle is twice in measure of the angle subtended at the circumference."
m(∠BOD) = 2(m∠BFD)
= 2(78°)
= 156°
Therefore, m(arc BD) = m∠BOD = 156°
Since, m(arc BD) + m(arc BFD) = 360°
156° + m(arc BFD) = 360°
m(arc BFD) = 360 - 156
= 204°
Since, "angle formed outside the circle by the intersection of two tangents measure half of the difference of the intercepted arcs".
m∠BCD = [tex]\frac{1}{2}[m(\text{arc BFD})-m(\text{arc BD})][/tex]
= [tex]\frac{1}{2}[204 - 156][/tex]
= 24°
Why is the radius 4?
Answers
Answer:
Please check explanations
Step-by-step explanation:
The equation of a circle can be represented as;
(x-h)^2 + (y-k)^2 = r^2
r is the radius while (h,k) represents the coordinates of the center
Thus, we have that;
(x-2)^2 + (y+3)^2
That would give;
x^2 - 4x + 4 + y^2 + 6y + 9
The sum of values with no coefficient is;
4 + 9 = 13
If we take this to the other side, we can have 13 + 3 = 16
The square root of this is then 4
Mathematically, we can therefore express the equation of the circle as;
(x-2)^2 + (y-+3)^2 = 4^2
By expansion, we will get the original given equation
