Answer:
A =530.66 cm^2
Step-by-step explanation:
A DVD is a circle so we can use the formula for area of a circle
A = pi r^2
We can find the radius from
r = d/2 where d is the diameter
r = 26/2
r = 13
A = pi *13^2
A = pi *169
Substituting in for pi
A = (3.14) * 169
A =530.66
I can’t see it sorry maybe it’s my device
Answer:
3 hours is 60×3=180
1/6 of 180 =180÷ 6= 30
30 mins is the answer
Step-by-step explanation:
if you want to find another position other than 1/6 like 4/6 then you can just times the answer in this case 30 by the amout u need in this case 4 so 4/6 would be 120 which is 2 hours
Step-by-step explanation:
to calculate circumference:

if the diameter is 16 then the radius would be 8.

to calculate the area of a circle:
