Answers

Answer 1
Answer:

Answer:

Step-by-step explanation:

Area of circle = πr²

= 3.14 * 12 * 12

= 452.16 sq. cm
Answer 2
Answer: Are = radius squared times pie so 12*12 = 144 so 144 times pi 3.14*144 = 452.16 is your answer

The diameter of the bottom of a lamp shade is twice the diameter of the top of the lamp shade. The top of the lamp shade has a 9-inch diameter. What’s the circumference of the bottom of the lamp shade? (Hint: Find the diameter of the bottom of the shade, then the circumference.)

Answers

Answer:

see explanation

Step-by-step explanation:

The circumference (C) is calculated as

C = πd ← d is the diameter

diameter = 2 × 9 = 18 in ( twice the top diameter ), thus

C = 18π in ← exact value ≈ 56.55 in ( to 2 dec. places )

The circumference of the bottom of the lamp shade is 56.55 inches

What is circumference of circle?

The circumference of a circle is the perimeter of the circle. It is the totallength of the boundary of the circle.

The diameter of top of shade(d₁) = 9-inch

The diameter of bottom of shade(d₂) = 2(d₁) = 2(9) = 18 inch

The circumference (C) of bottom of shade :

C = πd₂ = π × 18

C = 18π ≈ 56.55 inches

A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.

Given, Emerson is starting a new business. The product costs her $26.50.

She decides to mark the product up 30%.

∴ Her markup price will be 130% of $26.50, which is,

= (130/100)×$26.50.

= $34.45
