Hey there!!
- The area of a circle = πr²
The area is given as 196π
Hence,
196π = πr²
... r²= 196
... r = √196
... r = 14
<em>Hence, the radius is 14 cm. </em>
<em>Hope it helps!</em>
Answer:
Step-by-step explanation:
Answer:7.3
Step-by-step explanation:
adjacent =x
Hypotenuse =16
Φ=63
From SOHCAHTOA
CosΦ=adjacent ➗ hypotenuse
Cos63=x ➗ 16
Cross multiply
16 x Cos63=x
16 x 0.4540=x
7.264=x
x=7.264
Nearest tenth x=7.3
