The radius is half the diameter, so the formula would be r=d divided by 2
1.
s = 2(lw) + 2(lh) + 2(wh)
s = 2(2cmx3cm) + 2(2cmx4cm) + 2(3cmx4cm)
s = (2 x 6cm) + (2 x 8cm) + (2 x 12cm)
s = 12cm + 16cm + 24cm
s = 28cm + 24cm
s = 52cm^2
answer= 3rd option
2.
s = 2(lw) + 2(lh) + 2(wh)
s = 2(1mx10m) + 2(1mx5m) + 2(10mx5m)
s = (2 x 10m) + (2 x 5m) + (2 x 50m)
s = 20m + 10m + 100m
s = 30m + 100m
s = 130m^2
answer= 4th option
3.
s = 2(bh/2) + hw + sw + bw
s = 2(3ftx2ft/2) + (2ftx5ft) + (4ftx5ft) + (3ftx5ft)
s = 2(6ft/2) + 10ft + 20ft + 15ft
s = 2 x 3ft + 10ft + 35ft
s = 6ft + 45ft
s = 51ft^2
answer= 2nd option
4.
s = 6a^2
s = 6 x 2mm^2
s = 6 x 4mm
s = 24mm^2
answer= 3rd option
5.
s = 6a^2

5 1/4 x 4 2/4=21/4 x 18/4=21/4 x 9/2=189/8
Answer:189/8
Answer:
m∠x = 65°
m∠y = 81°
m∠z = 34°
Step-by-step explanation:
Since we have 2 transversals and a pair of parallel lines, we can see that at ∠A it equals 65°. If we use the Corresponding Angles Theorem, the m∠A = m∠x. Therefore, x = 65°
To find <em>y</em>, we know that a line is 180°. So, 180 - (65 + 34) = 81°
To find <em>z</em>, we know that all angles in a triangle add up to 180°. So, 180 - (81 + 65) = 34°. Alternatively to find <em>z</em>, we could use Alternate Interior Angles Theorem.
