Question

the length of equator of the globe is 22 cm find its surface area​

Answer 1

Answer:

Here you go :)

Step-by-step explanation:

Given:-

Length of equator of the globe is 22 cm.

⠀

To find:-

Surface area of the globe.

⠀

Solution:-

Length of the equator of the globe or circumference of a globe = 44cm

⠀

Let,

the radius be x.

⠀

☆Circumference of the globe = 2πr

→ 44 = 2 × 22/7 × x

→ x = 44 × 7/44

→ x = 7

⠀

Then,

☆Surface area of the globe = 4πr²

→ 4 × 22/7 × (7)²

→ 616 cm²

⠀

Hence,

the surface area of the globe is 616 cm².

⠀

⠀⠀⠀⠀⠀⠀Some Formulae

⠀

→ Area of square = (side)²

⠀

→ Area of rectangle = length × breadth

⠀

→ Area of triangle = ½ × base × height

⠀

→ Area of parallelogram = base × height

⠀

→ Area of Circle = πr²
