A shirt normally sells for $65. It was on sale for 45% off the regular price for 3 days. On the forth day it increased by 10% mo

sergiy2304 [10]

Answer:

$39.33 (rounded to nearest cent)

Step-by-step explanation:

Cost of shirt normally = $65

Cost of shirt for 3 days = $\frac{100-45}{100}$ × $65

= $\frac{55}{100}$ × $65

= $35.75

Cost of shirt on 4th day = $\frac{100+10}{100}$ × $35.75

= $\frac{110}{100}$ × $35.75

= $39.33 (rounded to nearest cent)

A sphere and a cylinder have the same radius and height. The volume of the cylinder is 27 xft?

attashe74 [19]

Answer:

Volume of sphere = $\frac{2}{3}(27\pi) ft^3$

Step-by-step explanation:

We are given that

Radius of sphere=Radius of cylinder=r

Height of sphere=Height of cylinder=h

Height of sphere=h=Diameter of sphere=2r

Volume of cylinder= $27\pi ft^3$

Volume of cylinder= $\pi r^2 h$

Using the formula

Volume of cylinder= $\pi r^2(2r)=2\pi r^3=27\pi$

Volume of sphere= $\frac{4}{3}\pi r^3$

Using the formula

Volume of sphere= $\frac{2}{3}\times 2\pi r^3=\frac{2}{3}(27\pi)$

Hence, the volume of sphere = $\frac{2}{3}(27\pi) ft^3$
