Answer:
the answer is 4 1/4 hours
Step-by-step explanation:
45+(80x2)=205+160=365
80_4=20+365=385
Volume of the sphere = (4/3) pi (5a)^3
Volume cone = (1/3) pi (3a)^2 * h (h = height).
(4/3) pi 125a^3 = (1/3) pi 9a^2 h
(4/3) * 125a^3 = (1/3) 9a^2 h
h = (4/3) * 125 a^3
-------------------- = 4 * 13.889 a
(1/3) 9 a^2
h = 55.56 cu units to nearest 1/100
Answer: B. 84 in²
Step-by-step explanation:
Divide the area into two regions: a rectangle and a trapezoid (depicted in the attached photo).
Find the area of the rectangle:
Area of a rectangle=length*width
Area of rectangle=(5 in)( 10 in)
Area of rectangle=50 in²
Next, calculate the area of the trapezoid:
Area of trapezoid=
h=10 in-6 in
h=4 in



Area of trapezoid=
Area of trapezoid=
Area of trapezoid=
Area of trapezoid=
Add the area of the trapezoid to the area of the rectangle to find the total area: 50 in²+34 in²=84 in²
