Answer:
88,306
Step-by-step explanation:
Multiplying times 7 steps:
Step 1. 8 x 7 = 56
Step 2. 1 x 7 = 7
Step 3. Add the 5 from step 1. 7 + 5 = 12
Step 4. 3 x 7 = 21
Step 5. Add the 1 from step 3. 21 + 1 = 22
Step 6. 1 x 7 = 7
Step 7. Add the 2 from step 5. 7 + 2 = 9
Equals = 9226
Steps for times 6:
Step 1. 6 x 8 = 48
Step 2. 1 x 6 = 6
Step 3. Add the 4 from step 3. 6 + 4 = 10
Step 4. 3 x 6 = 18
Step 5. Add the 1 from step 3. 18 + 1 = 19
Step 6. 1 x 6 = 6
Step 7. Add the 1 from step 5.
Equals = 79080
Now add the two 9226 + 79080 = 88, 306
Took me a while to work out and explain lol.
Let x = the smaller numberLet 3x + 15 = the larger numberx + 3x + 15 = 634x = 48x = 123(12) + 15 = 51
Answer:
1861.39 cm²
Step-by-step explanation:
Given:
d = 15 cm
radius (r) = ½(15) = 7.5 cm
Height = 32 cm
Surface area of a cylinder = 2πrh + 2πr²
Plug in the values
Surface area = 2*π*7.5*32 + 2*π*7.5²
= 1861.39 cm²
