(Please Hurry) Use 3. 14 as an approximation for it.

Which is the area of a circle with a radius of 6 cm?
A. 18. 84 cm
B. 28. 26 cm2
C. 37.68 cm2
D. 113.04 cm2
E. about 355 cm2

Answer 1

`\large{\fbox{D. 113.04 cm²}}`

Explanation:

Gɪᴠᴇɴ :-

• ❥ Rαdíus σf círclє ( r ) = 6 cm
• ❥ Vαluє σf pí π = 3.14

Tᴏ FɪɴD :-

• ❥ Αrєα σf círclє

SᴏʟᴜTɪᴏN :-

Tσ fínd αrєα σf círclє

wє usє fσrmulα

αrєα σf círclє = π × ( r ) ²

suвstítutє thє vαluє

αrєα σf círclє = 3.14 ×( 6 cm × 6 cm)

multíplч thє vαluє

αrєα σf círclє = 113.04 cm

Hєncє, αrєα σf círclє ís 113.04 cm ².

Answer 2

The formula for the area of a circle is:

Area = PI x r^2

You are given r (radius) and pi:

Area = 3.14 x 6^2

Area = 3.14 x 36

Area = 113.04 cm^2
