Answer:
Step-by-step explanation:
The formula for volume of a cylinder is
V = πr²h where r is the radius and h is the height.
We are given r = 5 and h = 2.5, plug those values in and simplify...
V = π(5²)(2.5)
V = π(25)(2.5)
V = 62.5π
Answer:
y = -2x + 6
Step-by-step explanation:
Since we already have the slope we just need to find the y-intercept.
To do that just plug in the point you were given. (1,4)
4 = -2(1) + b (b represents the y-intercept)
4 = -2 + b (add 2 on both sides)
6 = b
y = -2x + 6 is the equation
Hope this helps!!
Answer:
The area of shaded sector
Formula A = (θ / 360°) × πr²
θ=360°-140°=220°
r=18yd
We have A=(220/360)×3.14×(18)²
=621.72yd²
Area of sector is621.72yd².
Answer:
5/9 or 0.555
Step-by-step explanation:
(2/3)^2 + (1/3)^2
Multiply 2/3 twice and 1/3 twice, and then add both
4/9 + 1/9
5/9 or 0.5555
