Answer:

$c = 25.12m \\ a = 50.24 {m}^{2}$

Step-by-step explanation:

CIRCUMFERENCE

$2\pi \: r \\ 2 \times 3.14 \times 4 \\ = 25.12 m$

AREA

$\pi {r}^{2} \\ 3.14 \times 4 \times 4 \\ = 50.24 {m}^{2}$

hope this helps

Dennis can walk 2.833 miles each hour . About how far can he walk in 3 hours and 15 minutes

Bezzdna [24]

well, let's split the hours in minutes, so since 1 hr is 60 minutes, so he can walk 2.833 miles in 60 minutes, well, 3 hrs is 3*60 = 180 minutes, then we add 15 minutes, that's 195 minutes.

if he can walk 2.833 miles in 60 minutes, how long will it be for 195 minutes?

$\bf \begin{array}{ccll} miles&minutes\\ \cline{1-2} 2.833&60\\ x&195 \end{array}\implies \cfrac{2.833}{x}=\cfrac{60}{195}\implies \cfrac{2.833}{x}=\cfrac{4}{13} \\\\\\ 36.829=4x\implies \cfrac{36.829}{4}=x\implies 9.20725 = x$

A dinner table is a perfect circle with a diameter of 8 feet. With dinner plates that each a diameter of exactly 1 foot, how muc

Harlamova29_29 [7]

The area of the tablecloth showing is approximately 45.55 square feet

The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the circle in a two-dimensional plane is called as the area of the circle.

It is given that:-

The diameter of the dinner table, D = 8 feet

The diameter of each plate, d = 1 feet

The number of people at the dinner table = 6 people

The number of plates = 6 plates

The area of the table cloth, A₁ = π·D²/4

∴ A₁ = π × 8²/4

The area covered by the 6 plates, A₂ = 6·π·d²/4

A₂ = 6 × π × 1²/4

Let 'A' represent the area of the tablecloth showing when the table is set for six people, we have;

A = A₁ - A₂

∴ A = π × 8²/4 - 6 × π × 1²/4 ≈ 45.55 ft.²

Therefore the area of the tablecloth showing when the table is set for six people, A ≈ 45.55 ft.²

Let f(x)=3x+1 and g(x)=2x2−1 Find f(g(2)) 10 22 97 28

kupik [55]

Answer:

f(g(2)) = 22

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Algebra I

Composition of functions

Step-by-step explanation:

Step 1: Define

f(x) = 3x + 1

g(x) = 2x² - 1

Step 2: Find g(2)

Substitute: g(2) = 2(2)² - 1
Evaluate: g(2) = 2(4) - 1
Multiply: g(2) = 8 - 1
Subtract: g(2) = 7

Step 3: Find f(g(2))

Define: g(2) = 7
Rewrite: f(7)
Substitute: f(7) = 3(7) + 1
Multiply: f(7) = 21 + 1
Add: f(7) = 22

And we have our final answer!
