To convert degrees to radians, you need to multiply by
/180, so the radian measure of 84 is 84
/180, which can be simplified to 7
/15.
Answer:
189.3 cm^2
Step-by-step explanation:
split into a rectangle and a semi-circle
rectangle=LxW=10x15=150 cm^2
radius (r)=1/2 diameter=5 cm
semi-circle=1/2(pi)r^2=1/2(3.14)(5^2)=39.25 cm^2
150+39.25=189.25 cm^2
Answer:
A=3/4 B=3/5 C= 3/2 and/or 1 1/2 D=3/1 and/or 3
Step-by-step explanation:
The shapes are similar.
When two figures are similar, the ratios of the lengths of their corresponding sides are equal.
Therefore,
Simplify:
Cross multiply:
42(10+x) = 57x
420 + 42x = 57x
420 = 57x - 42x
420 = 15x
x = (420÷15)
x = 28
