34. A vessel is in the the form of a hemispherical bowl mounted by a hollow cylinder The diameter
Nostrana [21]

Answer:

V=20.85\ m^3

Step-by-step explanation:

Given that,

The vessel is in the the form of a hemispherical bowl mounted by a hollow cylinder.

The diameter  of the sphere is 3.5 m.

The height of the cylinder is 2 m

Height of the cylinder = Height of bowl− Radius of hemisphere

= 2 - (3.5/2)

= 0.25 m

The volume of the vessel is given by :

V = volume of hemispherical bowl + volume of cylinder

So,

V=\dfrac{2}{3}\pi r^3+\pi r^2 h\\\\V=\dfrac{2}{3}\times \dfrac{22}{7}\times (\dfrac{3.5}{2})^3+\dfrac{22}{7}\times (3.5)^2\times 0.25\\\\V=20.85\ m^3

So, the volume of the vessel is 20.85\ m^3.

Isaac buys 17 anti-pollution masks for £5.25 each.
mojhsa [17]

Answer:

A) Isaac should get £ 10.75 in change.

B) The price of the e-scooter in the sale is £ 366.3.

Step-by-step explanation:

A) Given that Isaac buys 17 anti-pollution masks for £ 5.25 each, and he pays with five £ 20 notes, to determine how much change Isaac should get, the following calculation must be performed:

(20 x 5) - (17 x 5.25) = X

100 - 89.25 = X

10.75 = X

So Isaac should get £ 10.75 in change.

B) Given that the normal price of an e-scooter is £ 370 and, in a sale, there is 1 off the normal price of the e-scooter, to determine the price of the e-scooter in the sale the following calculation must be performed:

370 - (370 x 0.01) = X

370 - 3.7 = X

366.3 = X

Thus, the price of the e-scooter in the sale is £ 366.3.
