Answer:
area of the merry go round =πr²
=22/7×3²
=28.28
answer is option D
Answer:
$18.00
Step-by-step explanation:
8 x 1.25 = 10
8 + 10 = 18
Fifth root of x is x^1/5 as an exponential expression. . This to the 7th power is
x ^(1/5 * 7) which is x^(7/5). Bringing this to the third power is x^ (21/5) which is your answer.
He has to drive around the track about 1.5 times.
We first find the circumference:
C = 2πr = 2(3.14)(1.6) = 10.048
We now divide 15 by this:
15/10.048 ≈ 1.5
