Answer:176.6cm2
Step-by-step explanation:
Pi*r^2
diameter is 15
divide by 2 is radius
It looks like you have

Substituting these in to the plane equation, we have

When
, we get the point

Answer:
PQ = 6.8
Step-by-step explanation:
Corresponding sides of similar shapes or figures are proportional to each other. Since ∆LMN ~ ∆OPQ, the ratio of their corresponding sides would therefore be equal. Thus:
LN/OQ = MN/PQ
LN = 5
OQ = 17
MN = 2
PQ = ?
Plug in the values
5/17 = 2/PQ
Cross multiply
5*PQ = 2*17
5*PQ = 34
PQ = 34/5
PQ = 6.8
Answer:
4 units squared
Step-by-step explanation:
The area of the rectangle is 9 units squared
The area of the two wedge-shaped triangles on the outside of the larger triangle is 3 units squared. The final triangle area is 2 units squared. Thus 9 - 5 = 4 units squared.
Answer:
$28.77
Step-by-step explanation:
What you do is the coupon for 10% off first which equaled 2.997, but you have to round to $3.00.
You minus 3*9.99 which equals $29.97 and $3.00 to get $26.97.
You then times $29.97 by 6% to get 1.80.
You then add it to $26.97.
You get $28.77.
