Answer:
Step-by-step explanation:
<u>Work:</u>
- 2(π x 21 x 21/2) + (π x 42 x 42/4) = Area of figure
- => π x 21 x 21 + (π x 42 x 42/4) = Area of figure
- => (22/7 x 21 x 21) + (22/7 x 21 x 21) = Area of figure
- => 2(22/7 x 21 x 21)
- => 2(22 x 3 x 21)
- => 2772 cm²
Hence, the area of the shape is 2772 cm².

Answer:
two dice are thrown, so S = {(1,1); (1,2); (1,3); ...;(6,5); (6,6)} ---> 36
the sum is 2, 4, 6
sum = 2 --> (1,1) ---> 1
= 4 --> (1,3); (2;2); (3,1) ---> 3
= 6 --> (1,5); (2,4); (3,3); (4;2); (5,1) ---> 5
⇒
= 9/36 = 1/4
Answer:
The image in the attached figure
Step-by-step explanation:
we know that
The dimensions of the image of the given triangle are equal to the original dimensions of the pre-image multiplied by the scale factor
In this problem the scale factor is 1/4
The height of the pre-image is 4 units
The base of the pre-image is 8 units
Find out the dimensions of the image
The height of the image is 
The base of the image is 
The image in the attached figure
Rational numbers are whole integers w no fractions. bc the square root of 72 is not a whole number, it is irrational
