Answer:
approximately 10
Step-by-step explanation:
Volume = 1/3h times
times radius square
1570 = 1/3 x 15 x 22/7 x 
1570 = 5 times
times 
1570 = 15.71
= 
99.9 = r^2
= r
≅10
Answer:
r=0.5
Step-by-step explanation:
0.125r+0.25r-0.0625=0.25+r
0.375r-0.0625=0.25+r
0.375r-r=0.25+0.0625
-0.625r=0.3125
r=0.3125/0.625
r=0.5
#3 is 2/4
#6 is 3/4
#10 is true
#4 is 4225
and those are the only ones I know
Hope I helped a little bit
