What is the nearest tenth of 28cm
Marianna [84]

Answer:

30cm

Step-by-step explanation:

"5 or above, give it shove. 4 or below, let it go." The number is the tenth's place is 2(since this isn't a decimal), and you need to round it by the number to it's right: which is 8. Since 8 is greater than 5, you change the 2 to a 3 and the 8 becomes a 0.

Find the circumference of the circle. Round to the nearest tenth if necessary.
NikAS [45]

Answer:

c.132

Step-by-step explanation:

so we are given the diameter which is 42m **the diameter is the straight line that passes through the middle of the circle**

but in order to find the circumference we need to find the radius **the radius is always half (1/2,0.5) of the diameter**

so we have to divide 42/2 which equals 21

now we need to set up the formula;

c=2πr/c=2xπxr  **when unknown variables such as 'r' are next to another mathematical numeral such as the pi symbol you don't really have to but the multiplication symbol between them**

c=2π21

=131.946891451

and in your case, it seems we must round to the tenths place so the nine then "becomes a ten" and you're left with 132

good luck :)

i hope this helps

have a good one !!
