This is just cylinder surface area, right? Equation for that would be 2πrh+2πr^2. If we input the data given from the image, it’d be (2 x π x 3.5 x 4)+(2 x π x 3.5 x 3.5). (4 is the height, and I found the radius by dividing the diameter, 7, in half, which is 3.5.) if u plug that into a calculator, u get 164.93.

Convert 2 5/6 to an improper fraction

bearhunter [10]

Multiply the denominator by the number in front of it and then add it to the numerator. (6•2=12+5=17). The denominator stays the same. Your answer is 17/6. Hope this helped!

How do i solve 51/2x-7=62

Nataly [62]

51/2x-7=62

Multiply both sides by 2x-7

$\frac{51}{2x-7}$ ×(2x-7) = 62(2x-7)

2. Switch sides

62(2x-7) = 51

3. Divide each side by 62

$\frac{62(2x-7)}{62}$ = $\frac{51}{62}$

4. Simplify

2x-7 = 51/62

5. Add 7 on both sides

2x-7+7 = (51/62)+7

6. Simplify

2x = 485/62

7. Divide both sides by 2

2x/2= 485/62/2

x= 485/124

Four more than a number is no more than thirteen

statuscvo [17]

The equation would be 4+x $\leq$ 13.
Subtract 4 from both sides. The four on the left would cancel out and the 13 on the right would now be a 9. Therefore, the answer is $x \leq 9$
