Round 125,458 to the nearest hundred thousand

Answers

To solve this you need to look at the number to the right of the hundred thousand place. So that would be "2" The rule is if that number is less than 5 round down, more than 5 round up.

So 125,458 = 100,000 to the nearest hundred thousand

How would I find the surface area of the cone in terms of pi? It has a radius of 7 cm and a slant height of 19 cm.

Answers

The formula is SA = \pi r^(2) + \pi rl.  r is the radius and l is the slant height.  In your case it would be 49\pi + 133\pi = 172\pi.

L.S.A = pi (7) (19) similar to 133*pi
3.14 * 133 similar to 417.62
similar to 417.62cm^2
