A medicine capsule is in the shape of a cylinder with two hemispheres stuck to each of its ends. The length of the entire capsul

mezya [45]

Diameter of the cylindrical portion of capsule = 5 mm
Length of the cylindrical portion of capsule = 14 mm - 5mm = 9 mm

Curved surface area of the cylindrical portion of capsule = $2\pi \: rh$
$= 2 \times \frac{22}{7} \times \frac{5}{2} \times 9 = \frac{990}{7} mm {}^{2}$
Curved surface area of two hemisphere = $4\pi \: r {}^{2}$
$= 4 \times \frac{22}{7} \times ( \frac{5}{2} ) {}^{2}$
$= 4 \times \frac{22}{7} \times \frac{25}{4} = \frac{550}{7} mm {}^{2}$

Surface area of the capsule = Curved surface area of cylindrical portion + Curved surface area of hemispherical ends
$= ( \frac{990}{7} + \frac{550}{7} ) \: mm {}^{2} = 220 \: mm {}^{2}$

The amount of time is takes dora to commute to work is always within 5 minutes of the average number of minutes the commute take

Maslowich

Answer:

The average time to commute to work is 25 minutes.

Step-by-step explanation:

If average time for Dora to commute to work is 5 mins. If she takes 45 mins to get to work then her overall average time to commute to work will change as the average consists of 2 or more figures. The average time to commute to work is 25 mins ((5+45)/2). The average of 5 mins and 45 mins is 25 mins. This is the overall average time she takes to commute to her work.
