Step-by-step explanation:

Exact area of circle = πr² = 196π sq ft

Approximate area of circle = 615 sq ft

Approximate circumference = 2πr = 88 ft

Answer:

615.75ft²

Step-by-step explanation:

A=πr²=π·14²≈615.75ft²

Answer:

A^2 + B^2 = C^2

Step-by-step explanation:

Your welcome!

Answer:

x = 13

Step-by-step explanation:

In order to solve this you need to know the Pythagorean theorem:

a^2 + b^2 = c^2

a - 1 side

b - 2nd side

c - hypoteneuse

Step 1: Find the missing side of the triangles

** Note both triangles are equal to each other as shown by the dashed line in both that signifies both sides are equal to each other, and the 90-degree angle there as well**

Solve:

17^2 + b^2 = 19^2

289 + b^2 = 361

361 - 289 = 72

√72 = √b^2

8.5 = b (approximately, to the tenth)

Step 2: Because both of the triangles are equal to each other, the missing side is equal to 8.5, but there are two of them, in order to determine x, you need to add both values together:

8.5 + 8.5 = 17  

Then you   subtract it from the base value: 31

31 - 17 = 13

Therefore, x = 13, as that is the remaining of the base.  

Answer:

solve it yourself

Step-by-step explanation:

length of ist part= 30 cm

breadth of ist part = 21 cm

area of ist part = 630 cm

diameter of 2nd part= 21 cm

area of 2nd part = ¼dπ

π= 22/7

= ¼× 21 ×22/7

=3×10.5

= 31.5cm²

total area = ist part +2nd part + 3rd part

=

Step-by-step explanation:

step 1. a circle with r = 2 has area of (pi)r^2 = (pi)(4) = 4pi

step 2. a circle with r = 3 has area of (pi)r^2 = (pi)(9) = 9pi

step 3. the area, A, of a circle is half the sum of the area of the circles with r = 2 and r = 3

step 4. A = (4pi + 9pi)/2 = 13pi/2 = 6.5(pi).

step 5. the answer is not 6.5 but is 6.5(pi) or 6.5 times pi.

Answer:

Taller because it is bigger and more likely to have greater volume

Step-by-step explanation:

its correct 100%

The correct statement is,

''The taller cylinder have the larger volume than shorter cylinder.''

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Will the shorter cylinder or taller cylinder have the larger volume.

Since, We know that;

The volume of a cylinder is calculated by multiplying the area of the base by the height.

And, since the height of the taller cylinder is greater than the shorter cylinder, it is likely to have a larger volume.

Thus, The taller cylinder have the larger volume than shorter cylinder.

Step-by-step explanation:

A number that would lie between -2.15 and -2.16 on the number line are 2.151.

Integers are arranged at equal intervals along horizontal straight lines called number lines. A number line can be used to represent every number in a series. The endpoints of this line go on forever. Some will have a defined beginning and end. It refers to those as closed number lines. Number lines might be alternatively left empty or blank. A number ladder is a vertical number line.

There are some possibilities would include the following:

2.151, 2.152, 2.153, 2.154, 2.155, 2.156, 2.157, 2.158, 2.159

therefore, the numbers that are between 2.15 and 2.16 are 2.151.
