netineya [11]

Answer:

Part A) The diameter of the rug is 10\ ft

Part B) The radius of the rug is r=5\ ft

Part C) The area of the rug is 78.5\ ft^{2}

Step-by-step explanation:

Part A) Find the diameter of the rug

we know that

The circumference of a circle (circular rug) is equal to

C=\pi D

where

D is the diameter

we have

C=31.4\ ft

\pi=3.14

substitute the values and solve for D

31.4=(3.14)D

D=31.4/(3.14)=10\ ft

Part B) Find the radius of the rug

we know that

The radius of a circle (circular rug) is half the diameter

we have

D=10\ ft

r=D/2

substitute

r=10/2=5\ ft

part C) What is the area the rug is covering?

The area of the circle (circular rug) is equal to

A=\pi r^{2}

we have

r=5\ ft

\pi=3.14

substitute

A=(3.14)(5)^{2}

A=78.5\ ft^{2}

Makovka662 [10]
Area de la base es un hexagono: Nota: asumiendo que 39 cm son el lado de un hexagono. Menuda pizza.

A = 3*sqrt(3)/2*a^2 = 3*sqrt(3)/2*39^2 = 3951.67391746839972 cm^2

Hay dos base y tapa, doble:

7903.34783493679944 cm^2

Luego los lados verticales:

6 * 39 * 4.7 = 1099.8 cm^2

TOtal = 9003.14783 = 9003.147 cm^2 = 9003.15 cm^2
