Answer:
Step-by-step explanation:
lateral area=πr²h=π×3²×6=54π sq. yards
surface area=2πr²+πr²h=2π×3²+54π=18π+54π=72π sq. yards
Answer: 80cm
Step-by-step explanation:
Given:
Radius r = 16cm
Radial distance x = 5 radians
Radian is a measure of angles.
1 radian = 180°/π
To convert radial distance to linear distance
Linear distance = radial distance × radius
d = xr
d = 5 × 16cm
d = 80cm
Answer:
940
Step-by-step explanation:
Since there is a 5 in the ones spot we round the number is the tens spot up by 1: 935 --> 940
Yes Jackie would have enough money to buy a CD player. So you would have to do 32.95 times that by 30% (.3) and would get 9.885 which you would round that to 9.89 dollars.
Answer:
Minimum quantity = q = 70.71units
Step-by-step explanation:
Give c(q)= 75+2q+0.015q^2
but average cost A(q) = c(q)/q
A(q) = 75/q + 2 + 0.015q
for minimum cost, differentiate A (q) wrt q
= -75/q2 + 0.015 = 0
q2 = 5000
q = 70.71units
