Answer:
Breadth=45 cm and Area = 3150
Step-by-step explanation:
Length= 70 cm and breadth =?
Perimeter=2(l+b)
or,230=2(70+b)
or,230=140+2b
or,230-140=2b
or,90/2=b
or,b=45cm
Breadth=45cm and Length=70cm
Area=l×b
=70×45
=3150cm^2
Answer:
Radius: 7.75
Volume: 1949.82
Step-by-step explanation:
The radius is half the diameter, so 15.5/2 is 7.75
The formula for a sphere is V=4/3 (πr^3). All that needs to be plugged in is the radius. You should be able to use a calculator for this problem, so the rounded answer is 1949.82.
