Answer:
The radius is 18 cm
Step-by-step explanation:
The formula for circumference with radius is
C = 2*pi*r
We know the circumference is 36 pi
36 pi = 2 * pi *r
Divide by pi
36 pi/pi = 2 * pi/pi *r
36 = 2r
Divide by 2
36/2 = 2r/2
18 = r
Answer:
The answer is D.
Step-by-step explanation:
Using Pythogaras' Theorem to find the value of x. The formula is, hypo.² = side² + side² :
side = 8 units
side = 12 ÷ 2
= 6 units
hypo.² = 8² + 6²
= 100
hypo. = √100
= 10
Answer:
1 1/4
1.25
Step-by-step explanation:
Answer:
V = 1980cm^2
Step-by-step explanation:
Volume of rectangle = LxWxH
V = 34 x 6 x 6
V = 1224cm^2
Volume of triangle = (BxHxL)/2
B = 34 - 16 = 18cm
H = 20 - 6 = 14cm
L = 6
V = (18x14x6)/2
V = (18x14x6)/2
V=1512/2 = 756cm^2
1224 + 756 = 1980cm^2
x = 57
