What is the approximate volume of a cone with a height of 11 ft and radius of 3 ft?Use 3.14 to approximate pi, and round answers to two decimal places if necessary. Actually ttype in 3.14 don't use the symbol because it adds more numbers
___ft3
$\pi$ don't use this do 3.14

Answers

Answer 1

Answer: Substitute the values of the radius (r=3), the height (h=11), and an approximation of Pi (3.14) into the formula to find the volume of the cone.
V≈+1/3⋅3.14⋅3^2⋅11

Simplify.
Write 3.14 as a fraction with denominator 1.
V≈+1/3⋅3.14/1

Combine 1/3 and 3.14/1 to get 3.14/3.
V≈+3.14/3

Replace back in to larger expression.
V≈+3.14/3⋅3^2⋅11

Divide 3.14 by 3 to get 1.04666667.
V≈+1.04666667⋅3^2⋅11

Raise 3 to the power of 2 to get 9.
V≈+1.04666667⋅9⋅11

Multiply 1.04666667 by 9 to get 9.42.
V≈+9.42⋅11

Multiply 9.42 by 11 to get 103.62.
V≈+103.62

Remove trailing zeros from 103.62.
V≈+103.62ft^3

Volume:
V≈+103.62ft^3

Answer 2

Answer: so volue of a cone=1/3 times (area of base) times height
area of base=circle so

find area of base/circle

pi times r^2
3.14 times 3^2
3.14 times 9
28.26

1/3 times 28.26 times 11=103.62 cm^3

A manufacturer wants to use a scale factor of 1.5 to enlarge a window. What will the area of the window be after it is enlarged?

Answers

The relationship between linear scale factor and area scale factor can be

used to find the area of the window after it is enlarged.

The area of the window after it is enlarged is 72 square feet

Reasons:

The length of the window = 4 feet

The width of the window = 8 feet

The scale factor the manufacturer wants to use, LSF = 1.5

Required:

The area of the window after it is enlarged

Solution:

The scale factor of area, Area SF = The square of the length scale factor, LSF²

Therefore;

Area SF = 1.5² = 2.25

Area of the window after it is enlarged = Original area × 2.25

The original area = 8 ft. × 4 ft. = 32 ft.²

Therefore;

Area of the window after it is enlarged = 32 ft.² × 2.25 = 72 ft.²

How do you solve (20.3×0.7)×7 with pemdas step by step

Answers

TheProfessor35's answer is correct, but here's a step by step as you asked. PEMDAS stands from Parentheses Exponents Multiplication Division Addition Subtraction. So, in the problem, you first solve the part inside the parentheses. Are there exponents? No, so we move on. Anything need to be multiplied? Yes, 20.3 x 0.7. That gives us 14.21. Now, there is nothing left in the parentheses to be divided, added, or subtracted, so we move on to the outside. We multiply 14.21 by 7 and get 99.47.

Start with parenthesis.

20.3 * 0.7 = 14.21
14.21*7 = 99.47

Answer: 99.47
