20% of a number is 1/5th of it so 50 × 5 is 250
Answer:
14
Step-by-step explanation:
area of sector = 153.9
or, (1/2) r²∅ = 153.9
or, r²∅ = 153.9 ×2
or, r²∅ = 307.8
or, r²× π/2 = 307.8
or, r² = 615.6/π
or, r² = 196
or, r=√196
r = 14
Answer:
105
Step-by-step explanation:
Well first you do 3x7=21
then 21x5= 5x20=100 + 5x1= 5
100+5=105
