First, you need to multiply 2*21cm, which gives us 42 cm.
Then we multiply it by π, or 22/7 in this case, and 22/7*42cm gives us 132 cm.
So the answer is: 132cm.

Step-by-step explanation:
Use Pythagorean theorem:
c² = a² + b²
Here, c = 42 and a = 31.
42² = 31² + b²
b = √803
b ≈ 28.3
Answer:
9x ≤ -37
Step-by-step explanation:
A product of a constant and a variable is indicted by writing the constant next to (typically, in front of) the variable. The symbol ≤ means "is less than or equal to". So ...
(the product of 9 and x) (is less than or equal to) -37
9x ≤ -37
3.2 x 10^-2 + 3.2 x 10^-4 + 2.8 x 10^-2
= 3.2 + 2.8
= 6 x 10^-2 + 3.2 x 10^-4
Convert 3.2 into fraction which is 16/5
And express with a positive exponent using “a^-n = 1/a^n” therefore
= 6 x 10^-2 + 16/5 x 1/10^4
= 6 x 1/10^2 + 16/5 x 10^4
= 6 x 1/100 + 16/5 x 10,000
Reduce 6 and 100 with the GCF ‘2’
Then reduce 16 and 10,000 with 16
= 3 x 1/50 + 1/5 x 625
Multiply
= 3/50 + 1/3125
Then add
The answer is
= 377/6250
= 0.06032
