Step-by-step explanation:
A = π 
A = π 
A = 49π
For the one you put in the comment...
The radius of a circle is 19cm find its area in terms of π
A = π 
A = π 1
A = 361π
For the other one you put in the comment
The radius of a circle is 4 cm find its area in terms of π
A = π 
A = π 
A = 16π
For the other one you put in the comment
The radius of a circle is 20 cm find its area in terms of π
A = π 
A = π 
A = 400π
Hope this helped!

The answer is 1561 yuans and 27 jiao.
you're given the pythagorean theorem, which is a^2 + b^2 = c^2.
what you're trying to find is ?, which is the number under the radical.
let's pretend one leg is a and the other is b.
a = 9
b = 10
so let's plug it into the equation. we get 9^2 + 10^2 = c^2
so that equals 81 + 100 = c^2
181 = c^2
so c will equal the square root of 181. therefore, ? = 181.
hope i helped! good luck.
Answer:
x = 50
Step-by-step explanation:
Let x be the original price.
He got 30% off
The discount is .30x
Subtract this from the original price to get the price he paid
x - .30x = price he paid
.70x = price he paid
.70x = 35
Divide each side by .7
.70x/.7 = 35/.7
x=50
