Answer:
Step-by-step explanation:
The radius of the circle is 34cm
r=34cm
Circumference of the circle is the same as perimeter of the circle and it is described as
P=2πr
Therefore,
P=2×22/7×34
P=213.714cm
The circumference of the circle is 213.714cm
Answer: 810
Step-by-step explanation:
first lets take down the information we were given,
height (h) of the pyramid should be 12 - 9 = 3
base (a) = 9
So we calculate the volume of a square pyramid
V = a²h/3
V = (9² × 3) / 3
v = (81 × 3) / 3
V = 81
now we calculate the volume of the cube using the formula
V = a³
V = 9³
V = 729
NOW to get the volume of the entire figure
we say
volume of square pyramid + volume of cube
81 + 729 = 810
