Lara is filling a jar with coffee powder. The diameter of the jar is 2.75 and the height she plans on filling the jar to is 4.6.
What is the area of the base?
Responses
A 7.56in^2
B 12.65in^2
C 1.89 pi in^2
D 5.5 pi in^2
How much space is there in the jar for Lara to fill with coffee powder?
A 34.79in^3
B 58.19in^3
C 8.69in pi^3
D 6.49in pi ^3
Area of the base = πr^2
Radius (r) = diameter / 2 = 2.75 / 2 = 1.375
Area of the base = π(1.375)^2 = 1.89 π in^2
So, the correct answer is C.
Volume of the jar = Area of the base x height
Volume of the jar = 1.89 π in^2 x 4.6 in = 8.69 π in^3
So, the correct answer is C.
