R = 14ft , D = 3 1/3 yd


A = (pi) (r^2)

A = (22/7)(14)^2

A = 616ft^2 / 616 square feet

Kinda hard for me to explain online.. Hopefully this makes sense.

Area of circle:

A = πr²

π = 22/7, or 3.14 (simplified)

'a line all the way across' means a diameter, which is 28 cm. To find the radius, divide the diameter by 2:

28/2 = 14

Plug in 14 (the radius) to r inside the equation:

A = πr²
A = π(14)²

14² = 196

A = π(196)

π = 3.14

A = 196(3.14)

A = 615.44

615.44cm² is the area of the circle

hope this helps

Use the way that kids use i.e trial and error method .

Solution:-

The set given by

\\ \rm\longmapsto \left\{32+n,\dfrac{n}{8},\sqrt{n+225}\right\}

Lets understand

  • See the first term any natural value will make it natural .

Come to 2nd one.

  • n should be a multiple of 8 to make it whole.

Come to third one

  • n should be a number which makes the sum a perfect square by which we get a natural no.We have to solve it w.r.t to 2nd one

Lets think

Nearest squares to 225 are 196 and 289

We can't take 196 as we have to take a positive one other wise it will come in terms of i.

Take 289

\\ \rm\longmapsto n+225=289

\\ \rm\longmapsto n=289-225=64

Its divisible by 8 .

Rewrite the set

\\ \rm\longmapsto \left\{64+32,\dfrac{64}{8},\sqrt{225+64}\right\}

\\ \rm\longmapsto \left\{96,8,\sqrt{289}\right\}

\\ \rm\longmapsto \left\{96,8,17\right\}

Hence n=64

= 13 + ( 14 x 11 )

= 13 + 154

= 167
