Answer:
Area = 270π inches squared. Volume = 550π inches cubed
Step-by-step explanation:
Surface Area:
Cylinder Area=2πrh+2πr^2= 180π+50π=230π inches squared.
Cone Area = πr(r+√(h^2+r^2)) = 5π(18) = 90π inches squared.
Total Area = 230π+90π = 320π inches squared.
Total Area - base = 320π-50π = 270π inches squared.
Volume:
Cylinder volume = πr^2h = 450π inches cubed
Cone volume = πr^2(h/3) = 100π inches cubed
Total Volume = 550π inches cubed
Answer: 3.33miles
Step-by-step explanation:
given data:
distance covered in first 15 minutes = 10 miles
time spent buying gas and some snacks = 10mins.
= 10/15 * (15 –10 )
= 3.33miles
jacob has traveled 3.3miles between 10 and 15 minutes.
Answer:
660 square feet
Step-by-step explanation:
1 chain = 66 feet
Length ( l ) = 66 feet
Breadth ( b ) = 10 feet
To find :
The area of a cricket pitch in square feet = ?
The area of a cricket pitch in square feet will be in the shape of rectangle.
Formula : -
Area of a rectangle = lb
Area of a rectangle
= 66 x 10
= 660 square feet
Therefore,
660 square feet is the area of a cricket pitch.
878/3 is 28 with a remainder of 10! The error is when they subtracted 258-248 wrong
