The formula for an area of a circle is A= pi(r)^2
so if you plug in 5 to r (because it’s the radius) you should get A= 78.5
Answer:
B. 1,188 cubic units
Step-by-step explanation:
First find the area of the base
A = 1/2b*h (this would only be half the base so our formula would be)
A = b*h (Now enter values)
A = (9)(6)
A = 54 (now plug this into the volume formula)
V = Ab * h
V = (54)(22)
V = 1,188 cubic units
13: 72.25
14: 52
For 14, you need to split the figure into a triangle and rectangle.
(1) 4/5
(2) 7/9
(3) 6/10
(4) 8/8 or 1 whole
(5) 8/9
