The circumference of a circle is 15π ft. What is the area, in square feet? Express your answer in terms of π.
DerKrebs [107]

Answer:

  • Area of the circle is 56.25π square feet.

Step-by-step explanation:

<u>Given that</u>:

  • The circumference of a circle is 15π ft.

<u>To Find</u>:

  • What is the area, in square feet?

<u>We know that</u>:

  • Circumference of a circle = 2πR
  • Area of a circle = πR²

Where,

  • Radius is denoted as R.

<u>Finding the radius of the circle</u>:

Circumference of a circle = 15π

⟶ 2πR = 15π

⟶ 2πR = 2π × 7.5

Cancelling 2π.

⟶ R = 7.5

∴ Radius of the circle = 7.5 ft.

<u>Finding the area of the circle</u>:

⟶ Area = πR²

⟶ Area = π(7.5)²

⟶ Area = π × 7.5 × 7.5

⟶ Area = π × 56.25

⟶ Area = 56.25π

∴ Area of the circle = 56.25π ft.²

In your biology class, your final grade is based on several things: a lab score, scores on two major tests, and your score on th
WARRIOR [948]

Answer:

Weighted\ Average =  73

Step-by-step explanation:

Given

Lab = 21\%

Tests = 25\%

Exam = 29\%

Lab\ Score = 60

First\ Test = 81

Second\ Test = 69

Exam = 79

Required

The weighted average

To do this, we simply multiply each score by the corresponding worth.

i.e.

Weighted\ Average =  Lab\ worth * Lab\ score + Tests\ worth * Tests\ score.....

So, we have:

Weighted\ Average =  21\% * 60 + 25\% * 81 + 25\% * 69 + 29\% * 79

Using a calculator, we have:

Weighted\ Average =  73.01

Weighted\ Average =  73 --- approximated
