Answer:

960

Step-by-step explanation:

This is a triangular prism. It has 5 faces. Two faces are congruent triangles. The other 3 faces are rectangles.

SA = 2 × ½bh + L₁W₁ + L₂W₂ + L₃W₃

SA = 2 × ½ × 10 in. × 24 in. + 10 in. × 12 in. + 26 in. × 12 in. + 24 in. × 12 in.

SA = 960 in.²

Find the measure of an angle whose supplement measures seventeen times its measure

Lilit [14]

supplement angles, sum = 180
lets x = angle
its supplement = 180 - x

x + 17x = 180
18x = 180
x = 10
180 -10 = 170

answer
angle = 10
its supplement = 170

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
