Answer:230m
2.59x10-10m
It is 1*1010 metres, or simply 1010 metres.
The area is 157 square meters rounded to the nearest whole number.
10M 10M 10M
1m = 100cm so 230m = 23000cm
The square root of 85 correct to the nearest tenth is 9.2
1 dam3 = 10m*10m*10m = 1000 m3.
If the fence is parallel and extends 10m from each end of the length of the pool, add 20m to the length of the pool to find the length of the fence; find the width of the fence in the same manner. Hence, 50 + 20 = 70m (length of fence); 25 + 20 = 45m (width of fence). 2(L + W) = Perimeter, so 2 x 115m = 230m perimeter
16m-10m = 6
1.5-10m = -8.5
This question is too poorly worded to distinguish the radius or diameter from the height.
It is correct, so 22.15 is already correct.
