Answer:

Perimeter: 61.41 units

Area: 136.68 units squared

Step-by-step explanation:

Circle Formulas

Circumference = 2πr

Area = πr^2

Perimeter

add all sides and 1/4 of the circumference of that circle

10 + 10 + 5 + 5  + 2π5

10 + 10 + 5 + 5 + 31.41

61.41

Area

How much space that shape takes up

10 x 10 x 3/4 = 75

π5^2 = 246.74

246.74 x 1/4 = 61.68

61.68 + 75 = 136.68

andrew11 [14]

Answer:

A) 57%

B) 16%

C) 53%

D) 57%

Step-by-step explanation:

Let R1 be students that attend class regularly

R2 be students that don't attend class regularly

A be students that receives A's in class

A) From the question A/R1 =57%

P(A/R1) = 0.57

B) From the question students that receive As that does not attend lectures regularly =16%

C) P(R2) = 1 -0.57 = 0.43

P(A) = P(A/R1) × P(R1) + P(A/R2)×P(R2)

P(A) = (0.57× 0.81) + (0.16×0

43)

P(A) = 0.46 + 0.0688= 0.53

The overall percentage that recieved A's = 53%

D) 57% recieved A's given that they attend class regularly.

Plug in the dimensions to the formula given using a handy dandy calculator for both problems. 

1. The diameter of the bottom of the cone is 4 so the radius (half that) is 2. Volume = 1/3 * pi * (2)² * 6
= 1/3 * pi * 4 * 6
= 1/3 * pi * 24
= 8 * pi
≈ 25.1327 cm³

2. They give you all you need, the radius.
Volume = 4/3 * pi * (6)³
= 4/3 * pi * 216
= 288 * pi
≈ 904.7787 in³
