Answer:
area = 175 cm^2
Step-by-step explanation:
area = base * height
area = 5 cm + 35 cm
area = 175 cm^2
Well in the bottom one x =1 and y=2
X-smallest
y middle
z largest
x+1=y
y+1=z
2x+3z=126
2x+ 3(y+1)=126
2x+3y+3=126
2x+3(x+1)=123
5x=120
x=24
y=25
z=26
Answer:
Step-by-step explanation:
Radius of outer circle = R = 9 cm
Radius of inner circle = r = 5 cm
Area of the shaded region = area of the outer circle - area of the inner circle.
= πR² - πr²
= π(R² - r²) = 3.14*(9² - 5²)
= 3.14 * (81- 25) = 3.14 * 56
= 175.84 cm²
Answer:
2/3
Step-by-step explanation:
Given : A geometric sequence : 18, 12, 8, 16/3,…
Solution :
Each term is found by multiplying the previous term by a constant in a Geometric Sequence .
In a Geometric Sequence common ratio is denoted by r
for n = 2
⇒
⇒
for n = 3
⇒
⇒
⇒
Thus the common ratio 'r' = 2/3
