Shera is building a cabinet she is making wooden braces for the corners of the cabinet. What is the surface area

1 answer:

7 0

The correct answer for the question that is being presented above is this one: "28 in^2."

We have to get the individual area of each surface.
A1 = 1*3*2 = 6
A2 = 1*3*2 = 6
A3 = 1*2*2 = 4
A4 = 2*3*2 = 12
Area = A1 + A2 + A3 + A4
Area = 6 + 6 + 4 + 12
Area = 28 in^2

In a sample of 800 U.S. adults, 219 think that most celebrities are good role models. Two U.S. adults are selected from this sa

shutvik [7]

Answer:

Step-by-step explanation:

P=(219/800)×(218/799)≈0.0747≈0.075

800-219=581

P=(581/800)×(580/799)≈0.527

P( 1 think role models and one thinks not role models)+P(both thinks they are role models)=(219/800)×(581/799)+(219/800)×(218/799)=(219×581+219×218)/(800×799)

=[219(581+218)]/(800×799)

=(219×799)/(800×799)

=219/800

=0.27375

=0.274

In this circle, the area of sector COD is 50.24 square units.

Bezzdna [24]

Answer:

Radius = 8 units

Length of arc AB = 8.37758 units

Step-by-step explanation:

The sector COD is 1/4 the size of the circle.

the vertex angle is 90° and a circle has 360° at the center.

So the area of sector COD/area of Circle = 90/360 = 1/4

This means the area of the circle is 4 * 50.24 = 200.96 square units

Area of circle = πr² where r is the radius
πr² = 200.96

r² = 200.96/ π = 63.9676 ≅ 64
Therefore r = √64 = 8 units

The circumference of the circle is 2πr = 16π units

arc AB has a vertex angle of 30°.

30°/360° = 1/6

So the length of the arc is 1/6th the circumference of the circle =

(1/6) * 16π = 2.67π units or 8.37758 units
