Answer:

The correct answer option is 153 $\pi mm^2$ .

Step-by-step explanation:

We are given a cylinder with a radius of 4.5 mm and a height of 17 mm and we are to find the lateral area of this cylinder.

We know that the formula of the lateral area of a cylinder is given by:

Lateral area of cylinder = $2 \pi r h$

Substituting the given values in the formula to get:

Lateral Area = $2\pi *4.5*17$ = 153 $\pi mm^2$

Answer:

The correct answer is option 3. 153π mm²

Step-by-step explanation:

Formula:-

Lateral surface area of cylinder = 2πrh

r - Radius of cylinder

h - Height of cylinder

To find the lateral surface area of cylinder

diameter of cylinder = 9 mm

radius, r = 9/2 = 4.5 mm and height, h = 17 mm

lateral surface area = 2πrh = 2 * π * 4.5 * 17 = 153π mm²

Therefore the lateral surface area = 153π mm²

The correct answer is option 3.

Claim: The measures of $\angle B$ and $\angle B'$ are equal

Answer: True

Explanation: Dilations preserve the shape of an image, so this means the angles are kept the same whether you shrink or enlarge the preimage.

====================================================

Claim: The coordinates of A and A' are the same

Answer: True

Explanation: The phrasing "dilating about point A" means that point A is the center of the universe, so to speak, in terms of this dilation operation. Point A is the fixed point that does not move while every other point does move. Because the scale factor is 2/3, which is less than 1, this means every other point comes closer to point A. So something like segment AB will get shorter.

148=3x+3+4x+1 solve

Andreas93 [3]

Answer: 20.57142857

Step-by-step explanation:

148 = 3x + 3 + 4x + 1

Step one: combine like terms

148 = 7x + 4

Step 2: Subtract the 4 over to 148

144 = 7x

Step 3: Divide 7 on both sides

20.57142857 = x

A few weeks into the deadly SARS (Severe Acute Respiratory Syndrome) epidemic in 2003, the number of cases was increasing by abo

DaniilM [7]

Answer: The required exponential model is $1804(1.04)^t$

Step-by-step explanation:

Since we have given that

Initial cases = 1804

Rate of growth = 4%

Since it is increasing exponentially,

So, it becomes,

$A=ab^t$

Here, a = 1804

b = $1+r=1+0.04=1.04$

So, it becomes,

$A=1804(1.04)^t$

Hence, the required exponential model is $1804(1.04)^t$
