Answer:
Surface area of the wood to be painted = ( + r ) - 16
Step-by-step explanation:
Surface area of a cone is given as the sum of the surface area and the area of its base.
i.e Surface area = + Lr
where: L is the length of its slant height and r is the radius.
Applying the Pythagoras theorem,
L =
Thus,
Surface area = r (r + )
The given cylindrical hole has a radius of 4 cm and depth 2 cm.
The area of one of its circular surfaces =
= ×
= 16
The surface area of the piece of wood to be painted = surface area of cone - area of cylindrical circular surface.
Surface area of the wood to be painted = r (r + ) - 16
Answer:
21,550
Step-by-step explanation:
An increase of 5% means the population is multiplied by 100% +5% = 1.05. This occurs each year for 12 years, so the multiplier is ...
1.05¹² ≈ 1.7958563
When the initial population is multiplied by this factor, it becomes ...
12,000×1.7958563 ≈ 21,550
Line D and C because they are not parallel but distorted or unsymmetrical
Can be expressed as y=0.55n
Answer:
okay so the first question says divide :40203 by 13
= after dividing the quotient comes as 3092
Step-by-step explanation:
then to verify the answer using division algorithm
the formula is as dividend = (q x d) + remainder
so the verification= 13 x 3092 + 7 = 4023
the second question says to find the difference between the pv of two 4's in 948475
the answer is 40000 - 400 = 39600ans.
the third question's answer will be:
amount mohan deposited in his savings Bank account= ₹35000
amount he withdrawed = ₹6245
therefore total amount of money left in his account =
₹28755ans.
Hope it helps!!!!!!!!!!
