Kobotan [32]
First let's find the area of the original rectangle:
12*5 = 60
Now for the new triangle:
1.25(12) * (1-0.2)(5)
15 * 4 = 60
There is no change in the rectangle.

Find the area of sector JKL. Enter your answer in terms of a fraction of π and rounded to the nearest hundredth.
Anna007 [38]

<u>Given</u>:

The radius of the circle is 4 cm.

The angle of the sector JKL is 135°

We need to determine the area of the sector JKL

<u>Area of the sector:</u>

The area of the sector can be determined using the formula,

A=\frac{\theta}{360^{\circ}} \times \pi r^{2}

Substituting \theta=135^{\circ} , r=4, we get;

A=\frac{135^{\circ}}{360^{\circ}} \times (3.14) (4)^{2}

A=\frac{3}{8} \times (3.14) (16)

A=\frac{150.72}{8}

A=18.84 \ cm^2

Thus, the area of the sector is 18.84 cm²

The diameter of a sphere is 4 centimeters. Which represents the volume of the sphere?
lord [1]

Answer:

V = 33.5 cm^3

Step-by-step explanation:

The volume of a sphere is given by

V=4/3 pi r^3

The diameter is 4

r= d/2

r =4/2 =2

V = 4/3 pi (2)^3

V = 4/3 pi 8

V = 32/3 pi

Assuming pi is approximated by 3.14

V = 32/3 (3.14)

   = 33.493333333 cm^3

To the nearest tenth

V = 33.5 cm^3
