Answer:
8 feet
Step-by-step explanation:
you use pythagoras so you do 6² + 4² =52. then you square root 52 which is 7.2 so she needs 8 feet.
Answer:
Approximately: 200.76π or 630.39
Step-by-step explanation:
Surface area for sphere formula: A = 4π(r^2)
36π = 4(r^2)
(36/4)π = [4(r^2)]/4
9π = r^2
28.26 = r^2 (since π equals 3.14)
√28.26 = √r^2
r ≈ 5.32
Volume for sphere formula: V = 4/3(π)(r^3)
V = 4/3(π)(5.32^3)
V ≈ 4/3(π)(150.57)
V ≈ 200.76π
or
V ≈ 630.39
Answer: 100 cell phones.
Step-by-step explanation:
The worker makes 2.5 phones an hour. 2.5 x 40 = 100.
Answer: 2 years
Step-by-step explanation:
If Interest= Principal x rate x time/100; then time is (100 × Interest)/(Principal × Rate)
From the question, old Principal is 5600, new principal =6720, the difference is the interest accrued.
Interest = 6720 - 5600 = Rs 1120
Rate = 8% = 8 ÷ 100 = 0.08
Time = x
Then, slot the values into the formula
Time= 100 x 1120 / 6720 x 8
= 112000/53760
=2.08
Time= 2years
