The radius of a circle is 4 feet. What is the area of a sector bounded by a 45° arc?
DIA [1.3K]

Answer:

Area = 6.28\  ft^2 or Area = 2  \pi\ ft^2

Step-by-step explanation:

Given

Radius, r = 4ft

Angle, \theta = 45

Required

Calculate the area of the sector

When angle is given in degrees, the area of sector is calculated as thus;

Area = \frac{\theta}{360} * \pi * r^2

Substitute\ r = 4\ and\ \theta = 45

Area = \frac{\theta}{360} * \pi * r^2 becomes

Area = \frac{45}{360} * \pi * 4^2

Area = \frac{45}{360} * \pi * 16

Area = \frac{45*16}{360} * \pi

Area = \frac{720}{360} * \pi

Area = 2 * \pi

Area = 2  \pi\ ft^2

The above is the area in terms of π

Solving further.... (Take π as 3.14)

Area = 2  \pi\ ft^2 becomes

Area = 2 * 3.14\  ft^2

Area = 6.28\  ft^2

Hence, the area of the sector is

Area = 6.28\  ft^2 or Area = 2  \pi\ ft^2

A truck that can carry no more than 7100 lb is being used to transport refrigerators and upright pianos. Each refrigerator weigh
pishuonlain [190]

Let x be the number of refrigerators

Y be the number of pianos

So the inequality:

300x + 475y < 7100

So substitute 12 and 8 to the inequality

300(12) + 475(8) < 7100

3600 + 3800 < 7100

7400 < 7100 is not true

So it will overload the truck

The area of a rectangular fountain is x2 + 9x + 20 square feet. A 3-foot walkway is built around the fountain. Find the dimensio
Leto [7]

Answer:

(x+11) by (x+10)

Step-by-step explanation:

We know that Area = Length x width

Given: Area = x²+9x+20

Lets sort this out first

Area = x²+5x + 4x + 20

Area = x(x+5) + 4(x+5)

Area = (x+5) (x+4)

Therefore, it is concluded that:

Length 'l' = (x+5) feet

Width 'w' = (x+4) feet

if a 3-foot walkway is built around the fountain, we'll add 3 feet on both sides

Therefore,

Outer Length = (x+5+3+3) = (x+11) feet

Outer Width = (x+4+3+3) = (x+10) feet

Answer:

The fountain is (x+5) by (x+4).  

dimensions of the outside border of the walkway are (x+11) by (x+10)
