3/20, 6/20, 9/20, 12/20 so the common difference is 3/20, ie each term is 3/20 greater than the term preceding it. Any arithmetic sequence can be expressed as:

a(n)=a+d(n-1), a=initial term, d=common difference, n=term number, in this case:

a(n)=3/20+(3/20)(n-1)

a(n)=3/20+3n/20-3/20

a(n)=3n/20 so the 5th term is:

a(4)=3*5/20=15/20=3/4

what is the surface area of cone with a diameter of 10 centimeters and a slant height of 12 centimeters round your answer to the

Oduvanchick [21]

The surface area of the cone is $266.9cm^2$

Explanation:

The diameter of the cone is 10 cms

Thus, the radius of the cone is given by

$r=\frac{d}{2} =\frac{10}{2} =5$

The slant height of the cone is 12 cms

The formula for surface area of the cone is given by

$S A=\pi r^{2}+\pi r l$

Substituting the values, we get,

$S A=(3.14)(5)^{2}+(3.14)(5)(12)$

$S A=(3.14)25+(3.14)(60)$

$SA=78.5+188.4$

$SA=266.9cm^2$

Thus, The surface area of the cone is $266.9cm^2$
