Answer:
The volume of a cylinder is 62.8 cm and the volume of a cone is 20.9 cm³ .
Step-by-step explanation:
Formula


Where r is the radius and h is the height .
As given
A cylinder and cone have the same height and radius. The height of each is 5 cm, and the radius is 2 cm.

Thus

= 62.8 cm³
Thus the volume of a cylinder is 62.8 cm³ .



= 20.9 (Approx) cm³
Thus the volume of a cone is 20.9 cm³ .
Therefore the volume of a cylinder is 62.8 cm and the volume of a cone is 20.9 cm³ .
Answer:
176
Step-by-step explanation:
88% = 88/100
88 × 2 = 176
176/200
Answer:
30 miles
Step-by-step explanation:
The rate is distance /time
50 /15 =10/3 miles per hour
To find the distance traveled in 9 minutes, multiply the rate by the time
distance = 10/3 *9 = 30
30 miles
Answer:
4 and 3
Step-by-step explanation:
Answer:
To help in solving exponential equations when relating the bases cannot be used
Step-by-step explanation:
Recall an equation of the form
from the expression
,
is the base and the power is
.
it is impossible to carryout the operation since the bases are not equal.
This is where we implore the help of logarithm which help us to bring the base to a come base i.e using the property below
.
Hence we can conclude that logarithm helps in solving equations when bases cannot easily be related.
