From a circular sheet of a radius of 14 cm, a circle of radius 7 cm is removed. Find the area of the remaining sheet. |
|
Answer» ONG>Given data : A circle of radius 7 cm is removed from a circular sheet of radius 14 cm. To FIND : Find the area of the remaining sheet ? Solution : Here we use formula of area of circle, ⟹ Area of circle = πr² {Here, r = radius and π = 22/7 (3.14)} ⟹ Area of circle = 22/7 * (7)² ⟹ Area of circle = 22/7 * 49 ⟹ Area of circle = 22 * 7 ⟹ Area of circle = 154 cm² Similarly, ⟹ Area of circular sheet = πr² ⟹ Area of circular sheet =22/7 * (14)² ⟹ Area of circular sheet = 22/7 * 196 ⟹ Area of circular sheet = 22 * 28 ⟹ Area of circular sheet = 616 cm² Now, ⟹ Area of remaining sheet = Area of circular sheet - Area of circle ⟹ Area of remaining sheet = 616 - 154 ⟹ Area of remaining sheet = 462 cm² Answer : Area of remaining circular sheet is 462 cm².

Answer» ider the given equation, sinθ+cosθ= 2
…(1) TAKING square both sides, sin 2 θ+cos 2 θ+2sinθcosθ=2 1+2sinθcosθ=2 2sinθcosθ=1 sinθcosθ= 2 1
……(2) Now, divided by cosθ in equation 1st , we GET tanθ+1= cosθ 2
….(3) Again divided by sinθ in equation 1st, we get 1+cotθ= sinθ 2
….(4) ADD equation 1st and 2nd , we get tanθ+cotθ+2= cosθ 2
+ sinθ 2
tanθ+cotθ= 2
.( sinθcosθ sinθ+cosθ

A:b+c=2:3,c:a+b=5:7 find a:c=? |
|
Answer» ong>Answer: Step-by-step EXPLANATION:
GIVEN:
a:b = 2:3 and b:c = 5:7
To find:
a:c
Solution:
In the given sum, a: b = 2:3 and b: c = 5:7
We know, Ratio is the QUANTITATIVE value between two values (here, between a and b, in the first case and between b and c in the SECOND case) that gives the number of times one value contains or is contained WITHIN the other value.
Hence, the ratio of two quantities can be represented in a fraction form, where the first number is the number in the NUMERATOR and the second number is the number in the denominator.
Thus the given ratio, when expressed as fraction, can be written as:
and
Thus, to find out a:c, we just have to multiply
