Bree made three identical birthday hats out of construction paper. Each was in the shape of a cone. The diameter of each hat was
1 answer:
Answer:
(C)261.12 Square Inches
Step-by-step explanation:
The diameter of the Cone Hat = 6.6 inches
Radius = Diameter/2=6.6/2=3.3 Inches
The slant height = 8.4 inches.
To determine how many square inches of construction paper did Bree need to make the three hats, we find the Curved Surface Area of the Cones.
Curved Surface Area of a Cone
Therefore, the area of paper used for the 3 hats
=3 X Area of One Hat

Answer:
41.24cm²
Step-by-step explanation:
See attachment for the figure
First is to find area of rectangle
Given:
Length of rectangle 'l'= 3cm
breadth of rectangle 'b'= 3cm
Area of rectangle= l x b= 3 x 3=> 9cm²
Next is to find the area of the circle
Given:
radius 'r'= 4cm
Area of circle= πr² => π4² =>50.24cm²
Required:
area of the shaded region=?
area of the shaded region= area of the circle - area of the rectangle
area of the shaded region= 50.24 -9 =>41.24cm²
Therefore, area of the shaded region is 41.24cm²
Answer:
Step-by-step explanation:
<u>Event A - spinning violet or yellow</u>
Assuming that the spinner has 4 different colors (red, orange, violet and yellow) - see attachment.
<u>Event B - rolling an even number</u>
Assuming the number cube has 6 sides numbered 1, 2, 3, 4, 5 and 6. Therefore, the even numbers are 2, 4 and 6.
Events A and B are <u>independent events</u> as the outcome of one event does not affect the outcome of the other event.
For independent events A and B:
To find P(A and B), substitute the found values of P(A) and P(B):
