Im pretty sure the value of x in this equation is -3 because -3 plus 5 would equal 2.
Step-by-step explanation:
(2³ × 2¹)²
(2⁶ × 2²)
for indices , × become +, plus
÷ become -, minus
so
2⁶+²
2⁸
we are given that
angle(ACF)=90
angle(ACB)=61
sum of all angles along any line is 180
so, we get
angle(ACF)+angle(ACD)=180
we can plug value
90+angle(ACD)=180
angle(ACD)=90
now, we can use formula
angle(ACD)=angle(ACB)+angle(BCD)
now, we can plug values
and we get
90=61+angle(BCD)
90-61=61-61+angle(BCD)
angle(BCD)=29................Answer
Given:
- Height of cylinder is 18.2 cm
- Radius of cylinder is 3 cm
To Find?
Solution:
Using formula:
- Surface area of cylinder = 2πr (h + r)
Substituting values in the formula:
- Hence, (B) 399.4 cm² is right answer.
