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.

Step-by-step explanation:
Answer:
14/8 or 14:8
Step-by-step explanation:
blue:brown=14:8
5 pigs: 3 chickens
pigs have four feet, so if 20 feet belong to the pigs, there's 5 pigs, because 5x4=20.
chickens have 2 feet, so if 6 feet belong to the chickens, there's 3 chickens, because 2x3=6.
Given:
Triangle Point coordinates or vertices:
A(16,0)
B(9,2)
C(2,0)
Required:
Side with slope -2/7
Solution:
To know which side has the slope required, we need to calculate the slope of each paired point by the two-point slope formula:
m = (y2-y1)/(x2-x1)
We first try points A and B.
m1 = (2-0)/(9-16)
m1 = -2/7
Thus, the side with the slope -2/7 is side AB.
