Answer:
22 pi cm ( 69.12 cm)
Step-by-step explanation:
pi * d = circumference = pi * 2 * r = pi * 2 * 11 = 22pi cm
For number 3, it is reciprocal
and for number 4, it is whole number
By convention, the first term of a sequence starts with n = 1 instead of n = 0. This is so n = 1 matches with 1st, n = 2 matches with 2nd, and so on.
In contrast, the y intercept always occurs when x = 0. So something like y = 3x+5 has a y intercept of 5 when you plug in x = 0.
An arithmetic sequence like f(n) = 2n+7 has its first term when n = 1. So the first term would be f(1) = 2(1)+7 = 9 instead of 7 as Hank claims.
The surface area of a rectangular prism is:
A = 2( (2*3) + (4*2) + (4*3) ) = 2( 6 + 8 + 12 ) = 2(26) = 52 so the answer for the first one is : 52in.^2
and for the second one u should know the surface area of a cube is:
6x ^2 so the answer is:
6x^2 square unites :)))
i hope this is helpful
have a nice day
