Step-by-step explanation:
area including track=area of 2 semi circles+area of rectangle
=2×1/2×π×46²+86×65
=2116 π+5590
area of grass=2×1/2×π×40²+80×65=1600π+5200
≈10226.55 m²
area of track=2116π+5590-1600π-5200
=516π+390
≈2011.06 m²
Answer:
14m
Step-by-step explanation:
Step1:
<u>C</u><u>onsider the first right angled triangle using Pythagoras Theorem:</u>
(hyponenus)^2 = (opposite)^2 + (adjacent)^2
20^2 = 12^2 + A^2
A^2 = 400 - 144 = 256
A = Square root of 256 = 16m
Step2:

Step-by-step explanation:
Answer:
<u>The original three-digit number is 417</u>
Step-by-step explanation:
Let's find out the solution to this problem, this way:
x = the two digits that are not 7
Original number = 10x+7
The value of the shifted number = 700 + x
Difference between the shifted number and the original number = 324
Therefore, we have:
324 = (700 + x) - (10x + 7)
324 = 700 + x - 10x - 7
9x = 693 - 324 (Like terms)
9x = 369
x = 369/9
x = 41
<u>The original three-digit number is 417</u>
