Haley has enlarged a 3-inch by 5-inch picture so that both the length and width are tripled. The area of the enlarged photo is h

77julia77 [94]

Answer:

9 times

Step-by-step explanation:

Area = length x breadth

area of picture not enlarged = 3 x 5 = 15in²

If length is tripled it becomes , 3 x 3 = 9in

If width is tripled, it becomes , 5 x 3 = 15in

Area of enlarged picture = 9in x 15in = 135in²

amount by which enlarged image is larger = 135in² /15in² = 9

What is the area of a sector with a central angle of 2π/9 radians and a radius of 16.7 ft?

Y_Kistochka [10]

Answer:

Area of the sector is 97.30 square feet.

Step-by-step explanation:

The area of the sector is given by

$A=(\frac{\theta}{2})r^2$

Plugging the known values in this formula to find the area of the sector

$A=(\frac{2\pi/9}{2})(16.7)^2\\\\A=\frac{2\pi}{18}\cdot16.7^2$

Use the value of π as 3.14

$A=\frac{2\cdot3.14}{18}\cdot16.7^2$

Simplifying, we get

$A=97.3016$

Rounded to the nearest hundredth, we get

$A=97.30$
