-4/8
Step-by-step explanation:
that's what my math says
Answer:
No
Step-by-step explanation:
No, because 0.7 is greater than 0.07 {Tip: Look for place of the decimal}
0.7 is written as 7/10 and 0.07 is written as 7/100
0.7 which is 7/10 is also written as 70/100 Hence, it clearly that 70/100 is greater than 7/100
0.7 is greater than 0.07 because to compare between two decimal numbers, you should look at the number after the decimal point and 7 is greater than 0 in the tenth place.

Step-by-step explanation:
the area of a track ? for a track we would normally look for the circumference. the area here is more that of an ice rink.
anyway, the area is the sum of the area of the rectangle in the middle and the areas of the 2 half-circles at both ends. since the half-circles are equally large, they are together the area of the full circle.
the length of the rectangle is 92.7 m.
the width of the rectangle is 2 times the radius (the diameter) of the circle = 2×31 = 62 m
the area of the rectangle is
92.7 × 62 = 5,747.4 m²
the area of the circle is
pi × r² = pi × 31² = pi × 961 = 3,019.07054... m²
the total area is then
5,747.4 + 3,019.07054... = 8,766.47054... m²
this is rounded to 1 DP
8,766.5 m²
