If the circumference of a circular ground is 616m, find its radius

98 m

Step-by-step explanation:

2πr = circumference = 616

2*22/7*r = 616

44/7*=616

r = 616*7/44

r = 14*7

r = 98 m

d. 8

step-by-step explanation:

the given radical expression is:

we can rewrite this as:

we express as square numbers to get;

the exponents will now cancel out to give.

the correct answer is d

step-by-step explanation:

the true statements are:

r = set of real numbers

n = set of natural numbers, 1,2,

w = n u{0} = {0,1,}
