Area  = 1/2 h(b + B)
1/2.10.(b + 12) = 100
5(b + 12) = 100
b + 12 = 100 ÷ 5
b + 12 = 20
b = 20 - 12
b = 8

8. If k = log, 3 then log, 48 =<br> 16<br> (1) 2k +3<br> (3) k +8<br> (2) 3k +1<br> (4) k +4
vekshin1

assuming you means k = log_2(3) [as log(2)3 is the same thing as 3log(2) due to multiplication being commutative]

given log(ab) = log(a) + log(b)

log_2(48) = log_2(3) + log_2(16)

The circumference of the target above is 6,895.4400000000 mm.
Sergio039 [100]

Diameter of the target is 2196 mm

Step-by-step explanation:

We are given Circumference of target = 6,895.4400000000 mm.

We need to find the diameter of target.

The formula used is:

C= 2\pi r

Putting values:

C=2\pi r\\6,895.4400000000=2*3.14*r\\6,895.4400000000=6.28*r\\r=\frac{6,895.4400000000}{6.28} \\r=1098\,\,mm \\

We know that Diameter = 2*radius

So, Finding Diameter:

Diameter = 2*radius\\Diameter = 2*1098\\Diameter = 2196\,\,mm

So, Diameter of the target is 2196 mm
