Answer:

The~surface ~area~of~this~cylinder~is~835.66cm^2.

Step-by-step explanation:

Greetings!

I'm~Isabelle~Williams~and~will~be~answering~your~question!

To~find~the~surface~of~a~cylinder,~we~use~the~formula~that~is:

\boxed{~A=2\pi r ~h+2\pi r^2~}

In~our~case~we~have:

=2\times \pi \times 7\times 12+2\times \pi \times 7^2

=835.66cm^2

Thus,~the~surface~area~of~this~cylinder~is~835.66cm^2.

Hope~this~helps~and~have~an~amazing~day~ahead!

A student council sells 44 bouquets for $176. Which equation represents the
vesna_86 [32]

Answer:

y = 4x

Step-by-step explanation:

Given

x = 44

y = 176

Required

Determine the relationship between x and y

First, we calculate the unit rate, using:

y = kx

Where k is the unit rate.

Substitute 176 for y and 44 for y

176 = k * 44

Divide both sides by 44

\frac{176}{44} = \frac{44*k}{44}

\frac{176}{44} = k

4 = k

k = 4

Substitute 4 for k in y = kx

y = 4x

Hence, the relationship between x and y is: y = 4x
