Answer:
198.5 cm²
Step-by-step explanation:
The figure is composed of a central rectangle and 2 congruent semi- circular ends, equivalent to 1 circle with diameter = 10 cm, thus radius of 5 cm
length of rectangle = 22 - 5 - 5 = 12 cm, thus
area of rectangle = 10 × 12 = 120 cm²
area of circle = πr² = π × 5² = 25π ≈ 78.5 cm² ( to 1 dec. place )
Total area = 120 + 78.5 = 198.5 cm²
Answer:
V= 64 ft^3
Step-by-step explanation:
The volume of a pyramide is given by the formula
V = 1/3 l*w*h
Given the l = 8 w = 4 and h = 6
V = 1/3 ( 8*4*6)
V = 1/3 ( 192)
V= 64 ft^3
Answer:
a. math and dance
b.1
c.Rita and Josh
Step-by-step explanation:
Hope you get it :)
You can multiply each fraction on both top and bottom so that they have 24 as the denominator. The equation becomes
subtract 16/24 to both sides and you get
now subtract 20/24 from both sides and
<u />
multiply 24 on both sides
-26=21m
and divide by 21 on both sides
m=-26/21 or -1.24
