Answer:
132 cm
Step-by-step explanation:
The circumference of a circle is given by
C = 2 * pi*r
Using 22/7 as pi
C = 2 * 22/7*21
= 132 cm
Answer:
f(x)=5000(1+0.05)^x
Step-by-step explanation:
Use the formula: f(x)=P(1+b)^x
P is principal or y-intercept. 5000 is principal.
b is the percentage in decimal form. 0.05 is b.
x is time, in this case years. Since there is not a certain number of years leave x as x.
f(x)=5000(1+0.05)^x

Answer:
A of each triangular base = 6 in²
A of both bases = 12 in²
Lateral A = 96 in²
Surface area = 108 in²
Step-by-step explanation:
<em>Area of each triangular base</em>
1/2(3)(4) = 1/2(12) = 6
<em>Area of both bases</em>
6*2 = 12
<em>Lateral Area</em>
(8)(3) + (8)(4) + (8)(5)
24 + 32 + 40
96
<em>Total Surface area</em>
96 + 12 = 108 in²
