The radius of the circle,
Pi × r² = 144 pi
r ² = 144
r = 12
The area of the sector,
60 / 360 × pi × 12² = 144/6 × 22/7 or 3.142
= 75. 43 or 24 pi
Answer:
Step-by-step explanation:
Formula for area of a triangle:
Height x Base /2
Base (b) = h +4
Height = h
h + 4 x h /2 = 30cm
=> h +4 x h = 60
=> h+4h =60
=> 5h = 60
=> h = 12
Height = 12
Base = 12 +4 = 16
Answer:
Easy, it's A.
5 more can be written as 5+ or +5. W is the width, so 5 more than the width is written as 5+w
Answer:
Step-by-step explanation:
<em>2( 2x + 6 ) + 2( x - 3 ) ≤ 66</em>
3x - 3 ≤ 33
x ≤ 10
x ∈ ( - ∞ , 10]
4x-6
A product means you have to multiply so the product of four and a number is 4 times x so 4x
A difference means you have to substraction a number from another number. So -6
