The answer is A. 2 and 4
Reason:
To formula for circumference is 2 x r x pi
2 x 2 = 4, 2 x 4 = 8and 4 + 8 = 12
Area is r ^2 x pi
2 ^2 = 4, 4^2 = 16 and 4 + 16 = 20
Multiply each number by 4
1*4= 4
4*4=16
16*4= 64
64*4= 256
256*4= 1024
Answer: 4
Answer:
x = 5 , y = 5
Step-by-step explanation:
Using the sine and cosine ratios in the right triangle and exact values.
sin30° = 
, cos30° = 
, then
sin30°= 
= 
= ( cross- multiply )
2x = 10 ( divide both sides by 2 )
x = 5
and
cos30° = 
= 
= ( cross- multiply )
2y = 10 ( divide both sides by 2 )
y = 5
Answer:
x² - 16
Step-by-step explanation:
Use the FOIL method here where
F = first
O = outer
I = inner
L = last
F = x * x = x²
O = -4 * x = -4x
I = 4 * x = 4x
L = -4 * 4 = -16
Combine the terms to get x² - 16.
Answer:
Your required answer is option is {20}.
Step-by-step explanation:
Hey, there!!
The reason for above answer is we generally find intersections among the sets by extracting the common elements of the sets.
Here,
R = {10,15,20}
S = {20,25}.
Now, 20 is common im both so,
R intersection S = {20}.
