A = <span>π r^2
r^2 = A/</span><span>π
r^2 = 530.93 / 3.14
r^2 = 169.08
r = 13
C = 2 </span><span>π r
C = 2 (3.14)(13)
C = 81.64
answer
81.64 m</span>
Answer:
6.4
Step-by-step explanation:
The given triangle is a Right Angled Triangle with right angle at E.
So, measure of angle E = 90 degrees
measure of angle D = 62 degrees
measure of side FE = 12
We have to find the measure of side DE. Note that side DE is adjacent to Angle D and side FE is opposite to angle D. So we can use tangent ratio to find the measure of DE.

Therefore, the value of DE, rounded to nearest tenth is 6.4
Answer:
3 shirts
Step-by-step explanation:
production cost: c = 28 + 3s
c=cost
3s= 3 shirts
28= dollars she has to add of her own money to be even with the amount she lost making the shirts
money earned= m = 10s
m=money earned from sales
10s= 10 shirts
Answer:
y = 6
Step-by-step explanation:
If x varies inversely proportional as y.
, k is constant of proportionality
or
k = xy
When x = 3 and y = 10
k = 3×10
k = 30
Put x = 5,

So, the value of y is 6 when x is 5.
