Answer:
3(4+n) = 12+n is an equation that could be used.
12n = 12+n
11n = 12
n= 1+1/11
Step-by-step explanation:
Answer:
a) 5:3
b) 7.5:5.3
Step-by-step explanation:
150min : 90min (1 and a half hour)
10 : 6
5 : 3
150 × 10 mm : 1060 mm
1500 : 1060
750 : 530
7.5 : 5.3
Given:
Radius of the cylinder = 2 cm
Height of the cylinder = 3 cm
To find:
The surface area of the cylinder.
Solution:
The surface area of a cylinder is:

Where, r is the radius and h is the height of the cylinder.
Putting
, we get



Therefore, the surface area of the cylinder is 62.8 square cm.
The reflexive property of equality simply states that a value is equal to itself.
