Answer:

Volume of a cylinder = 549.5 cm³

Step-by-step explanation:

Volume of a cylinder = πr²h

Where,

π = 3.14

Radius, r = 5 cm

Height, h = 7 cm

Volume of a cylinder = πr²h

= 3.14 * (5 cm)² * 7 cm

= 3.14 * 25 cm² * 7 cm

= 549.5 cm³

Volume of a cylinder = 549.5 cm³

After eating a meal at a restaurant, we decided to tip 25%, building a grand total of $87.50. What was the price before the tip?
CaHeK987 [17]

Answer:

65.62

Step-by-step explanation:

Given:

After eating a meal at a restaurant, we decided to tip 25%, building a grand total of $87.50.

To find:

Price before tip

Solution:

87.50 × 25% = 21.875

~Round~: 21.875 to 21.88

87.50 - 21 .88 = 65.62

Thus the price before the tip is 65.62

Check Answer:

<em>Formula: Higher number - Lower number ÷ original number × 100</em>

<em>Solve: </em>

<em>87.50 - 65.62 = 21.88</em>

<em>21.88 ÷ 87.50=0.25005714285</em>

<em>0.25005714285 × 100 = 25.0057142857</em>

<em>Round - 25%</em>

 if angle RZT=110, angle RZS=3s, and angle TZS=8s, what are angle RZS and angle TZS?
skelet666 [1.2K]
8s-3s=5s
5s=110
Divide both sides by 5 => s=22
RZS = 3s = 3(22) = 66
TZS= 8s = 8(22) = 176
