Step-by-step explanation:
then put 1/4 as t into the equations and see, if left and right side are equal. if not, then the answer option is wrong.
and you will see that 2t = 1/2 is the right answer.
because
2×1/4 = 1/2
2/4 = 1/2
correct.
Answer:
Step-by-step explanation:
first we need to calculate the area of isosceles triangle having sides 48cm, 48cm and 30cm
a = 48
b= 30
Area of isosceles triangle using only sides = ½[√(a^2 − b^2 /4) × b]
= 1/2*30√( 48² - 1/4×30²)
=1/2*30√ (2304 -225)
=684sq cm
cost required to make umbrella= 10*684*5
= 3<em>4200</em>
Answer:
Step-by-step explanation:
We are given that
Side of base=4 cm
l=w=4 cm
Height,h=12 cm
We have to find the rate at which the water level rising when the water level is 4 cm.
Volume of pyramid=
Substitute the value
Differentiate w.r.t t
Substitute the values
Multiply the numerator x numerator then you multiply denominator x denominator
