Answer:
(-9,-10)
Step-by-step explanation:
Total area =2triangles+3rctangles
rectangles is small ok so
we can consider the 3 rectangles as 1 big reectangle with base 5+12+13=30 and height 8
area=30*8=240
the 2 triangles
the height is 5 becasue it has to to match with the 5 on the small rectangle
base is 12
2 of them
aera=2*1/2*12*5=60
so total
240+60=300
total surfacea area is 300 in^2
4t=r
a=pir^2
sub 4t for r
a=pi(4t)^2
a=pi16t^2
a(t)=16pi(t^2)
A. a(t)=16pi(t^2)
B. sub 4 for t
a(4)=16pi4^2
a(4)=16pi16
a(4)=16*16*3.14
a(4)=803.84 square units
A. a(t)=16pi(t^2)
B. 803.84 square units
C the answer is C because you have to do that before anything
