Hi , the answer is 52% , because 13 divided by 25 equals to 0.52 , we move the decimal two spaces to the right , so the answer is 52.
first you need to mulitply 13 x 3 which is 39, then subtract 2 which is 37.
A or area will increase as r increases.
r^2 = r×r which means the r value is doubling increasing the area
Answer:
The answer to your question is 10 in
Step-by-step explanation:
Data
Circumference = 20π in
Radius = x
Formula
Circumference = πd
Process
1.- Equal the formula to the circumference
πd = 20π
2.- Solve for d
d = 20π / π
3.- Simplification
d = 20
4.- Find the radius
r = d/2
r = 20/2
r = 10 in
Answer:
30 degree
Step-by-step explanation:
acb is 60 equilateral triangle
then dac angle is 120 double of centre angle
triangle dac is isoceles so 2 into angle acd=180-120
then acd =30
