U can use the Pythagorean theorem which is (a^2 + b^2 = c^2) It'll help you a lot
9/10 + 8/100
9/10 + 2×4/25×4
Common denominator is 50.
9/10 + 2/25.
5×9/5×10 + 2×2/2×25
45/50 + 4/50
= 49/50
Answer:
1/2
Step-by-step explanation:
R(t) = 4t
A(r) = π(r^2)
a) A(t) = A[r(t)] = π[r(t)]^2 = π[4t]^2 = 16π(t^2)
b) t = 4,
A(4) = 16*3.14*(16)^2 = 12,861.44
Answer: the first one
Step-by-step explanation: the number is 42 45 45 46 and 48 are all close together while the number 16 is off to the whole other side
